I think its minimal enough to not effect handling much, but enough to throw off the OEM rotation... also if I do go with the lower profile the wheel well gap will be bigger and look odd (even though I'm lowered a bit)


too heavy though! These are the lightest wheels I can find 16.7lbs & 17.1 lbs the tires are pretty light too 28.xxlbs & 30lbs... plus they look pretty good.

Thanks for the feedback

 

I would get some KUMHO ECSTA MX tires...

cheaper than the Toyo's... better performing IMHO... specially for CA... it doesnt rain much here (except this weekend), and they are a much grabbier tire...

 

I have Kumho ECSTA now (on OEM 17)... cost benefit is good, but I have heard really good reviews (read and from people I know) about the Toyos... plus they are lighter than most tires... I'm gonna try the T1Rs this time. Thanks for the suggestion.

 

Ecsta MX? there are a few different ECSTA's ...

Their tread is like this...

 

245/45/18 is what i have on my Z track wheels.

It is the OEM Size on the 8.5 inch wheels

 

That's the oem size for the rear.

Mike,
You can run either the 40 series or 45 up front. 2% is within tolerance so it wont really mess anything up, i ran a 245/40 all around for the longest time. If you're not lowered too much then i'd go with the 45 series though, just to fill in some gap.

the more I think about it, Wei (and others) made a good point about possible flex from the taller sidewall... I was trying to match rotational speed with the 275/40 rear and 45 matches... but I should consider flex on hard cornering... and you have brought up a good point about wheel well gap (obviously I don’t want to rub)... the pic is current drop - I don't intend to go lower... the tires are 235/50/17... there's slightly less gap in front than rear, so maybe 40 profile would be better?

If I go 245/40 rotation is 2.3% faster than OEM (and quite a bit off from the 275/40 rear I'm considering)... So now I'm thinking 255/40 for the front, which is only 1/1% faster rotation than OEM (only .3" smaller diameter) - but more rolling resistance...


Damn it! I think this is one of the reasons I've waited so long to do this

Grant, what do you think about (f)255/40/18 and (r)275/40/18 ?

Here's a pic for gap reference:

 

255/40 would work good as well.
