255/50r16s, or 275/40r17. Cause i heard a thicker tire wall is better but then again the 275s are a bit wider.

 

It depends on what you are looking for. With slicks, the R16's will enable the tire to wrinkle more therefore giving you more traction. On the other hand a hard compound tire on the R16's will not perform as well as a nice sticky compound on the R17's.

The 16's will be better for the track. The 17's will be great for cornering but the ride will be more harsh.

What are you using the car for? Street, strip, autoX, that sort of thing. I assume that this is a street machine though.

 

i wanna get tires which will help my .60 foot times the best. Im thinking about getting kuhmo supras 255/50r16s on my stock 16*8 inch rims. But then i was also thinking maybe throwing 17*9s on there in mind that the 275/40r17s might be better?

 

If you want good 60' times then go with 15" rims and a drag slick. Even a DOT slick will be better but I don't recommend them for the street if you wish to keep them in good condition for the track.

A tall rim, small sidewall, tire won't hook up the same way since the sidewall is so small. A hard launch needs some sidewall to take the shock of the launch.

Small sidewall tires are designed for cornering where the tire won't roll over on itself in the hard corners.

Those 275's are wider but are also smaller in height by almost 1/2".

 

aight thanks, im gonna stick with my stock rims then.
