Track Tyres

[noone]

Tried searching but not much luck running 18's with 245's (street tyres)but just brought a set of 32GTR stockers with plans to run re55 225/50/16's but am a little worried that even with stickier tyres 225 may be a little smallish.

Still running stock brakes on the gtr so dont need 18's for anything other than looks (for now at least)

but will smaller width and diameter + bigger sidewalls be quicker or slower.

Just hoping to get some opinions from others who mighta tried this.

bigger sidewalls = a touch slower

less width =a touch slower

also weight, whats heavier, your 18's with semis or your 16's with semis?

[Beer Baron]

they may have the same size sidewalls? if you have 245/45 and you want to run 225/50 that is pretty much the same sidewall size. well 2mm difference (ie 8/10ths of fvk all).

they will be miles better than your 245 street tyres. plus 16s are cheap.

Hmmm interesting thread, will def watch and see what others say as this is probably a good way to run decent tyres on a track day without killing your street ones..

does anyone else feel that the Re55 is like running around on a tractor tyre? Dont get me wrong they give good grip its just that super wide groove make it almost like a cleted tyre :-) at slow speeds

Well they are noisy as all hell at about 80-90km/h & when they are pressured correctly the ride is pretty terrible.

Thats what I figured the stockys were cheap too

That makes it sound so appealing

Not sure bout the weight have pretty stuffed semi's on em now so so will try n find a set of scales to compare

my 18's are only ROH DriftR's so not exactly light I reckon maybe the forged stockers would be lighter.

Thanks for the opinions an Sorry for the slow replys have been away from the computer for a bit!

Would anyone suggest anything over the RE55s or is that going to open a whole nuther can a worms

IMO RE55s are the best street legal semi slicks available in terms of both grip and longevity.

for reference to tyre widths, when I went from 255s to 285s on the rear, I gained 0.75 seconds around the QR sprint circuit. now I have 305 full slicks on the way, THAT will be interesting

hoosiers have a DOT number stamped on them and two small lines through them. 295 wide 40% profile 17"rim

Hey Noone ,

I just bought semi's for my car and the advice i got is that although they might be smaller they'll handle the horsepower I have mine are 205/45/16 , RE55's should have a stiff sidewall so i think for you it'll be a question of will they handle the horsepower you have?If you have too much you'll fry'em , also the compound type(hard/medium/soft) will have a bearing on weather they'll do the job or not. cheers

re55s on 16"s will hose street tyres on 18"s, not even close...they will be seconds per lap quicker.

I compared good street tyres (falken fk451 in 18s) vs re55s on 17s and they were 3 seconds per lap quicker on Eastern Creek, 1.57 vs 1.54. Same car, same driver, 3 weeks apart.

The extra grip in the re55s makes the difference. They have super stiff sidewalls compared to road tyres which reduces any disadvantage from wheel diamter, and smaller wheels are lighter too. And smaller wheels = much cheaper tyres there is a big premium for tyres on big wheels.

ive got RE55's 205/55/16 on 7.5inch rims and there is 3 second difference over my road tyres
