Tyre help

[philw99]

Can someone confirm my calculations are correct?

Got new wheels ordered

Rota GTR in Gunmetal 18x9.5" 5x114mm ET30

 

now need some tyres, i'm thinking 255 on the rear and 245 on the front? this sound ok/good idea?

Calculation:

or should i go 45 all round??

Many Thanks

Phil

Personally I'd be looking for staggered width wheels and going for 245/40 front and 275/40 rear.

 

Captain has sold some 18" wheels recently which had 245/40 and 275/35 tyres on, you could ask him what he thought about going for a lower profile on the back.

i reckon 255 40 18 on the front, and 275 40 18 at the rear - differs to the original sizes by +0.34% and 0.00% respectively...

You want to keep the 20mm stagger F to R if at all possible, else you'll end up inducing either understeer or oversteer (in your example).

Wheels have arrived

 

 

Still investigating tyres.. been told to look at bigger than 255 at the rear. anyone got any comments on this?

 

Typical me can't find Vredestein tyres in the size i want

Tyres ordered

Gone for vredestein as a lot of the Supra lads really like them.

 

Hopefully will get the new wheels on me z next week

So what sizes did you get?

[philw99]

245 40 18 front 255 40 18 rear. Wanted 265 on the back but the price put me off. Might get them next time.

Your TCS may get twitchy times with those sizes.

[philw99]

That bad hey

vredestein don't appear to do a 265

Your TCS may get twitchy times with those sizes.

Should be 245 and 275 , 245 is quite stretched on a 9.5j rim

When you bought the wheels didn't they suggest the right tyres...
