[Mk2] [Turbo] Pls help me choose correct tyre sizes for 17" Alloys

[freak_in_cage]

Hi Guys,

My friend has recently acquired a mk2 tubby and before we go on a track day he may need new rears. Im trying to convince him to have 4 new ones but will have to see how the money is.

He has 17" alloys on the car, current tyre sizes are:

205 40 R17
235 40 R17

Will these sizes be in keeping with the originals to ensure suitable handling?

I wasn't really able to understand this thread

Many thanks to all you people who seem to understand this tyre mumbo jumbo!! [/quote]

I use 215 40 front and 235 40 rear on 8 " rims

It handles fine

not a good use of an 8inch rim though I do use the same front tyre on thesame sized rim, wish I'd bought a 7inch front

good point fellas- TBH i dont know how wide they are.

How can i measure this? Will there be lettering inside the alloy somewhere? Or must i remove the tyre?

Apologies for the ignorance

the width and ET could be anywhere, but is generally on the hub part of the wheel, normally behind the wheel.
so wheel off to look at the hub side.

tbh, ive seen peeps run those rear sizes on a 7 or 8 inch rim with no problems.

he will want tyres which offer a good price:performance ratio.....

this seems to be either Proxy T1-R or Kumho KU31s but im trying to find what sizes they come in........

will have a look inside the allow- thx GTS Chris

normally a printed number followed by letter(s) j


i always use a minimum of a 225 on an 8j rim
