alright i'm ordering some 15x 8 rota slips for the front of my car and i dunno what offset i should run so i wont have any problems.. they come in a +20 +35 +40 .. its going on the front of a 98 integra turboed.. i dont want really any camber cause i need traction.. let me have some ideas.. thanks

 

anybody have any ideas??

 

You're doing things ***-backwards. FIRST decide on what size tires you're going to use, and THEN find out what widths they can be mounted on.

The only 15" tire size that can safely be mounted on 15x8 wheels on an Integra is 225/45-15, and most of the tires that size are competition/race tires. If you're planning on doing this for track use, go for it! Otherwise, if you want street tires, you're going to want to get tires that are either 195/55-15 or 205/50-15, and neither of those sizes can safely be mounted on 15x8 wheels; get 15x6, 15x6.5, or 15x7 wheels.

For street use, treadwidth is not a big factor in performance and grip; the main factor is the make/model of tire you buy, as reflected in its design (tread pattern, compound, construction, etc). If you're really concerned about getting the most performance and grip for your high-horsepower application, worry about buying better, stickier tires, rather than wider tires. These are the stickiest 15" street tires you can get for your Integra:

Dunlop Direzza Sport Z1 Star Spec 195/55-15 or 205/50-15
Bridgestone Potenza RE-11 205/50-15
Yokohama Advan Neova AD08 205/50-15
Kumho Ecsta XS 205/50-15
Toyo Proxes R1R 195/55-15 or 205/50-15

 

If traction for DD is really what he cares about, then he should follow nsxtasy's advice.

 

it'll be very little daily use.. more track and just when ever a friend finds me a race on the street. it'll have a mickey thompson street slicks on it... or slicks..

 

First, don't race on the street.

Since you're not going to use these much on the street, by all means consider competition tires - drag radials or slicks for the DRAGSTRIP, or R compound track tires for the TRACK. However, even with competition tires, you still need to do things in the proper order:

First decide on what diameter wheels to get (e.g. 15").

Second decide on what size and kind of tires you're going to mount on them, based on what works best on your car.

Third look up the specs for the tire and see what wheel widths it can be mounted on.

Finally look up what offsets that wheel diameter and width is offered in, and find out which offset gives you the greatest clearance in the wheel wells.

Don't start with the wheel width or offset before you know anything about the tires; otherwise you could get stuck with wheels whose size won't work with the tires you need to buy. For example, you can get BFGoodrich drag radials in 205/50-15, but they need to be mounted on wheels 5.5-7.5 inches wide, not 15x8. You can look up these specs for whatever tires you're considering, including slicks.
