Hi,
I spoke to someone who felt 8 X 16 inch wheels with 245's front & rear was a good way to go. I have the same size wheels & tires on my 87 na, why not on the 88 turbo? He said he wore out front tires first with 7's & 8"s and unless he replaced the rear at the same time there was uneven grip. My turbo is fairly new to me, but it looks like the front tires will be gone when there is still some life left in the rear. Being able to rotate tires from front to rear sounds like a good idea for added life. I am a DE addict and tires seem to wear out fairly quickly. I run 2 Lbs less in the front now with street tires. It is fairly neutral, and sometimes loose, like when the boost kicks in. The next tires will probably be Toyo Proxy RA-1's. I want the car to be neutral. Seventeen inch wheels would be better I am sure, but the wheels and tires would no doubt cost more. Cost is an factor. If 8's front & rear is the way to go, why did Porsche not do this? Any thoughts?
Thanks,
Norm

I run 8 in front and rear with RA-1's on the track, and quite like it. Front is lowered some, not a lot, and there's no rubbing. With my setup, the car is quite neutral.

I guess the common answer to the why? question is that smaller tires on the front promote understeer, which the insurance industry likes.

im running 8x16's all around and i like it- 245/45/16's RA-1's. I had to dial my rear sway to full soft to get rid of the oversteer from the larger front tires, but she does great now. With stock or less than MO30 sways you prob wont have to adjust anything.

i think the staggered wheels suit the rear engine cars and thats why they're everywhere and i'm sure there a fashion item as well .I think i will end up with 17x8.5 all round if i can get some more 8.5 .
even if it is not the completely ideal handling set up the other benefits out way any talk against it if the tire wear is a bit uneven you rotate the tires . you can have a matching spare or pair of you can buy a set of tyres when there on sale . I've been considering ceyanne rim sets for this reason . i have boxter S rims but i'd prefer somthing as common as dog poo as now its hard for me to match up a set of 4 8.5
I've seen several of the more serius guys complain of elevated front tir temps on the track.

Hans from Holland who races his car suggests using same sized tyre front and rear to combat understeer through the tyre temps. He's talking about large format rubber too. 285's and upwards all round. Must be fun reverse parking. lol.

I run 8" with 245 tires all around on my n/a and 9" with 255 on my 951S.

Anything less than 245's up front on a ~3000lb rwd sports car is weaksauce IMO. 9's or 9.5's and 255's all around is an even better route IMO, but 245's is fine as well. 205's and 225's up front just doesn't give you quite the same handling and turn in capability. This is speaking street tires of course as slicks is a completely different subject. The only reason any manufacturer does that is the aformentioned understeer it promotes.
