Hi guys,

I need to change my rears and was wondering what would be the best size in your opinion?

Currently I have 235/40/17, should I keep this size or should I pick another one?

Cheers
Kostya

i have 235/45/17 on my rims at the rear, got a S15 there is also a tyre calculator in the technical area on the main index of the site...

I wouldn't go over a 225 on an 8 inch rim. Any smaller and it will be a bit stretched (which is ok up to a point), Any bigger and it will start to bulge out a bit (which i'm not a fan of).

235s sit with square sidewalls on an 8" wide rim.

235/40/17 will be slightly smaller than stock rolling diametre, whereas a 235/45/17 will be slightly larger.

I use 235/45/17 personally.

235/45/17 - as the local falcodores use this size alot, should prove to be easier in find the right tyre as its common.

but I guess 235/40 wpuld handle better than 235/45 right?

There are other things you can look at into tyre performance first, rather then a 5% decrease in profile size.

You can try buying better compound for a start before anything else

maybe 0.01% better?

you can go down to 215 on 8" (I have this right now on the fornt of mine) but the sidewalls taper a bit. 235/40 were on before and were just right IMHO. A 45 section gives rubbing problems if you've lowered your car.

Ive found a 235/40/17 feels better on the back than a 235/45/17

wouldnt a slightly stretched tyre provide better turn in response due to less tyre wall flex at a higher G turning?

Sure would. Ive gone from 225/40/18 on an 8.5" rim to 225/50's on a 16x7.5 rim and the amount of sidewall movement at high speed gets a bit scarey since there was none with the previous stretched tyres on bigger rims

that's assuming that you're not overcoming the grip level of the tread itself already.

factory recommended width for an 8" rim is a 235. I run 235/45/R17's all 'round on my wagon,and they work well enough. this is also a common-as size,so they're cheaper to come by.
