Discussion and technical advice the SW20 MR2. 3S-GTE, 3S-GE, 3S-FE etc
Anything and everything to do with maintenance, modifications and electrical is in here for the Mk2.
Looking to replace my rear tyres as the idiot who owned it before put 205/40/17 all round.
Fronts are fine
But with the rears I was looking at getting 225/40/17 which from what I have read are fine but the tyres I want to get are Toyo T1-R and they don't do that size but they do a a 235/40/17 or a 225/45/17
If I get the 235's I will have to up the fronts to 215 right?
But if I get the 225's they are up from 40 to 45, Is this that much of an issue?
Don't want to spend a huge about just some semi decent tyres.
Thanks!
Might be just as cheap buying a set of 2nd hand alloy wheels with good tyres, failing that, http://www.oponeo.co.uk/?gclid=CM2_kM2K ... tAod72AAJg
Cheapest by quite a long way
235's will be fine for the rears depending on rim widths, i'm sure whatever size is on the front will be fine, it's not as if you are running WOT round a race track all the time
Thanks Martin,
Yeah I will need a new set of wheels at some point! Thinking lenso samurai d1r but for now.....
225/40/17 seems to be a incredibly rare size?
My main concern / question is would using a 45 instead of 40 at the rear have a negative effect on handling? I notice people tend to go down to a 35....
Thanks
35 profile is simply to keep the rolling radius of the wheel/tyre combo the same as stock....
On that link above, you can play with the tyre profile to see how much the speedo over-reads by.
Yeah I thought that would be why, apologies for the stupid questions. Never really cared about tyres sizes on all my other cars I have owned so my knowledge is very limited
So basically increasing to a 45 would mean the speedo will over read slightly ( not that bothered as have a GPS unit wired in ) And will also mean that there will be more flex on the tyre wall? But I guess this can be countered by slightly increasing tyre pressure?
Thanks.

No such thing as a stupid question! Yeah, 45 profile on a 17 would over-read on the speedo due to the difference in rolling radius compared to the original wheel/tyre. In addition to this, you could have problems with arch/suspension/tyre clearance if the tyre profile is too big. I personally wouldn't go larger than a 40 profile front and back on 17s.
Thanks dude! yeah had a think and its also lowered on tein super street coilovers so will probably be best trying to get hold of some 235/40/17!
Seem to be so much more expensive than the 225
Anyone got some suggestions that will be similar to the Toyo T1-R's
Thanks
hmmm, everywhere I am looking it seems that the 235 is double the price of the 225
I guess I will have to measure to see if I can fit a 45 profile without rubbing. Literally cant find a 225/40/17 anywhere

Lol not going to be going to be tracking much / if at all dude, I need to work out if I have a 7j or 7.5j rim
If 7.5j I will go for 235/40
If 7j I will go for the 225/45 ( can not find a 40 anywhere )
Done a bit of looking and checked reviews, in order cheapest to most expensive.
Kumho KU39 ( apparently pretty good ) £67 a tyre
Toyo Proxes T1 Sport ( meant to be better than the T1R ) £84 a tyre
Goodyear Eagle F1 ( heard a lot of good things about these ) £91 a tyre
p.s remember mine is an N/A so not going to be breaking any speed records any time soon
