Tyre Size

I've had a search and cant seem to find the answer for stock 17" wheels.

What size tyres can i fit as the rears on my car need replacing.....

And is the psi the same all round? 36?

Anyone>? Hoping to get these done today.....

Is it the factory sizes you're after?

front - 235/45/17

rear - 255/40/17

Did you conduct your search in Russian?

Reply number 1 indicates that they are 235/45/17 front and 255/40/17 rear.

I have run my Supras (varying tyre sizes, types etc.) at 30psi with no issue.

I have run my Supras (varying tyre sizes, types etc.) at 30psi with no issue.

I typed in tyre size 17 :/

Ok so 30psi, i thought they were meant to be much higher than that on stock 17's.

would i be ok running 255/45/17 on the rear?

I run 32psi on those tyre sizes with no problems.

I was told 36psi.....

Anyone know about the slight increase in tyre size?

If you open the drivers door and look on the door shut panel there should be a sticker that tells you all the info.

I run 36psi for long motorway drives, but 34 for normal round town or spirited driving.

I run stock tyre sizes with 36psi up front and 34psi on the rears

Im not looking to change the width, increase the profile from 40 to 45. Not out of choice out of value for money when it comes to tyre.

*Edit*

Sorry the first link says its a 3.93% difference, so im guessing that is a straight no no to do then...

But if someone in the no could comment that would be great. on the limit and got a very long drive down south tomorrow and only tyres i can get off shelf near me at a cost suitable are 45 profile.

Ok I still can't find an answer. The tyre place has said that going up to 45 profile on the rear will be fine. Is this correct. There is a hell of a difference in price!

If not does anyone have some stock 17inch rear tyres for sale?

It would gear the car up going to a 45 profile, your speedo will be out too. I'd also imagine your geo would need setting up again to account the size change.

I understand your working to a cost but bare in mind with Supra's tyres wouldn't be a place I'd cut cost

Its purely the fact that i can't get a tyre in the size that is on the car at the moment, unless i buy online bt places are funny about fitting them then. It had 45 on before and i swapped to 40's but these are now nearly dead. So just need some fresh rubber that isn't 300 quid a tire.

Ok thanks.

Could i use a 265/40/17

rather than a 255/40/17 on the rear?
