Tyres; those black round rubber things that through the contact patch of a business card, hold you and your precious little rocket ship to the road. Probably should put a bit thought into which ones you buy hey? Good Idea :p

The 250 is fitted with wheels are designed to take a 110/70 front tyre and a 140/70 (or more rarely 140/60) rear tyre, although many people have put a 150/60 tyre on the rear (although it is designed for a wider rim that what’s on the 250.
There are a few opinions around on what size works the best, as nicked from the old thread.
“Some argue that the 150/60-17 rear tyre may suit the track better (with slower turn in but better stability), and also that a 140/70-17 rear profile may "tip in" quicker and be better for the street (less contact patch = less resistance = better fuel economy etc). I have used a 140/60-17 and I would recommend not getting it if you want to corner briskly, as it.. err, runs out of tread”
Moving to the 150 section rear however does open up a much wider range of brands to choose from, although many of the tyres are design for bigger bikes with more horsepower, and higher speed ratings (V:240kph, Z:240kph ,W:270kph) This poses a problem as the 250 may struggle to sufficiently work the tyre to maintain the proper temperature for optimum grip. So it is best to try and stick with a tyre that is H(210) rated and designed to work with bikes with less power.

There are 2 main ranges to pick in terms of usage, Sport and Touring/Commuting.
Sport tyres have a softer compound offering up more grip, at the expense of durability. Sport tyres also a more aggressive, V shaped or triangular, profile which lends itself to faster tip in speeds and more edge grip.
Touring tyres have a harder compound, or in many cases today a multi-compound rubber which provides added durability, whilst sacrificing the overall grip that a sport tyre provides. The profile on touring tyres tends to be more rounded which leads to a more docile handling (softer tip in speed and less rapid change of direction).

Now I’ve tried to keep my personal opinions out of the above size rant, now I’ll throw in my 2cents.
Personally I stick with the 140 section rear, The tip in and change of direction speed over that 150 is nice. And there is plenty of edge grip and stability even pushing them at the track.
I have found that using 150 section tyres pinched onto the rim of the 250 to work pretty well under most circumstances. However when pushing them hard at the track I have found that I’m not wearing them all the way to the edge of the tyre, even though my footpegs and fairings are slowly grinding themselves away. This seems to cup them out just short of the edge, which seems to diminish edge grip. (though I’m sure someone’s going to disagree with me)

So let’s throw up a list.

Sport- Bridgestone BT-090

[Comes in both 140 and 150 section rears]

http://mc.bridgestone.co.jp/en/products/battlax/bt090.html
Bridgestone’s small bike sport tyre, my personal favourite. Offers loads of grip, has a nice aggressive profile with leans the bike very quickly. These tyres can be a bit hard to track down as they are imported as a racing product, and most tyre places have never heard of them but racing suppliers should be able to get them no dramas. (At least this has been my experience)

Sport- Dunlop GPR-a10

[Comes in both 140 and 150 section rears]

http://www.dunlopmotorcycle.eu/dunlop_euen/mc/tyres/on_road/Sportmax_GPR_Alpha_10.jsp
Dunlop’s small bike go fast tyre. Loads of grip, a bit more docile on the handling that what the Bridgestone’s are but still a great tyre, can’t really go wrong.

Sport- Bridgestone BT-003 RS
[Comes in both 140 and 150 section rears]

http://mc.bridgestone.co.jp/en/products/battlax/bt003rs.html
Supposedly the successor to the above BT-090s, I’ve yet to see a set in the wild, so can’t really comment.
Listed as sport/middle sport on the Bridgestone webpage, along with the 090’s

Touring- Bridgestone BT-45
[Comes in both 140 and 150 section rears]

Offering a dual compound rear these tyres are durable enough to put up with constant long commutes without squaring off too rapidly, but with a softer shoulder that has no problems providing laps of knee down fun at the track.
A pretty standard tyre, any tyre place will be able to get them without issue.

Sport- Michelin Pilot Power
[Comes in 150 section rear only]

http://www.michelinmotorcycle.com/index.cfm?event=pilotpower
A long time staple bike tyre, has been used one everything at some stage or another. A few people on the forum have used Powers with success.

Oh Good God In Heaven Why- Dunlop GT501-Arrowmax

The Arrowmax, AKA Arrowstax, Rings of telfon, rings of wood, hey my tractor has tyres like that.
Ok to be just a touch fair, these tyres that come fitted on most bikes are proberly already 10+ years old and whatever oil was in them has long since buggered off down to the pub with its mates, leaving a lonley shell of rubber that has long since degraded into some kind of plastic that has the co-efficent of friction of astro glide. (astromaxs, perhaps?) Though since they offer next to no grip, they never wear out, burnouts have been known to create smoke out of the road rather than damage the tyre.
Even with this legendary hardness which is in the running to knock diamonds off the top stop on the Rockwell list. There have been reports of people getting their knee down on these tyres which in itself is impressive, but also been able to get it back up while still moving and not ending upside down in a ditch on fire.

These are the kind of tyres Casey Stoner wishes he had on his bike to at least give him a half decent excuse as to why he fell off this time.

Disagreement anyone? :p


Thatll do just for the moment, If anyone would like to do a quick little tyre blurb, feel free and I can throw it in here. Also anyone that has any questions on the black rings of life, shoot, I'll see if I can answer them and keep expanding this section.

Dont forget Michelin Pilot Activ's, come in 110/70 and 140/70...

I am running these at the moment on my CBR and they are a bloody good tyre! Also H rated, and cheaper (slightly) than Pilot Power's.

Pirelli Demons, as a step up from BT-45 and arrowmaxes have been a very good investment. I managed to get these fitted at $300 for both and did some commuting on them and track time. For commuting they are a little soft and will not last as long as the bt45's, these demons are best left for spirited riding or track time. On the track they will ball up quickly (not sure what effectthat has except for wear) and are great for grip. They do need to be warmed up for maximum use just like any tyre and this takes about five minutes on a regular tempurature road or 12 minutes on a cold day in Brisbane which is about 17 degrees air temperature. I can comment that these Tyres tip in very well with a 140 rear even compared to the bt-45's which are a great tyre in themselves. Expect a tyre life of around a year with twisty rideouts every second weekend and regular commuting depending on your riding style. At the price I got them they are excellent value over the bt-090's ( around 50-75 $ saving ) with similar performance. It is pretty unanimous knowledge that the BT-45's are a great all rounder for commuting and twisties with a long lifespan, and these pirellis are a good step up from those for when you develop your confidence with the cbr250.

I've managed to get my knee down with the arrowstax before I pulled the bike apart. It happened with my kick stand down in the garage as I was dismounting the bike.
I tried to do a burnout on them on my last ride, but it didn't work. useless.
I still haven't bought my new tyres, but am looking for either bt-45s, and now from what cbrpledge wrote, perhaps some Pirelli Sport Demons.

Hey guys, im relatively new to the forum, been browsing for a few weeks since i bought an MC19. Its my first road bike and get my L's in 2 weeks (im 28). Anyway was readin up about tyres on the old forum and all the negative comments about the arrowmax's, only to go check my bike and found it has them fitted. They have about 50% tread left and the bike will only be used for weekend joyrides so ive been wondering if they are actually as bad as everyone says and if i should replace them now, or ride on them for a few more months while im learning to handle a road bike and then change them?
And as i said it will only be used for weekend joyrides so what would be the best tyres to replace them with if im not worried about wear.

If you can afford to get new tyres for your bike then it is one of the best investments you can make for yourself. You might want to keep them on to see how it goes, they've worked so far right? It's really up to you, a lot of people would just leave them and save up instead of spending money but I advise you get a better tyre as soon as you can, arrowmaxes are only hindrance to forwarding your riding skills and won't allow you to discover the limits you can push the bike to. You know the tyres are substandard and will ride accordingly, and no doubt some of your ride outs will be on cooler mornings especially being winter. I wouldn't risk it personally

well mine came with arrowstax and i've been riding them since
learnt on it and yeah
the thing was, for some reason i never looked at my tyres till like last week, so i never realised how close to skidding i was :p

haha nah they're not that bad
but during wet weather they're terrible
so if its raining either slow down when you approach lights or speed through them
if you try and stop and your going fairly fast, god save you

EDIT: of course if you've got a lot of money to spend, get them replaced
