So I have a set of staggered Borbet A's i was looking to get new tires on.. I live in NJ and our roads are pretty shit for the most part. What size tires would be recommended without too much stretch?

A's were built from 15" to 18".

[Mystikal]

Are there any other tires out there I can get?

Nope. You need those sizes.

For a 17x10 wheel what range of offsets will work in the rear of the e30?

I assume it is pretty narrow, so using the Brocks in the post above would it be ET20 +/- ??

+20 is about dead-on. Very little space left to the trailing arms.

Hello,
I'm looking to put 235-40-17 tires (star specs, maybe rcomp in the future?) on my car.
I have an early model with e36m3 front suspension and inline6 z3 hubs on stock trailing arms in the back. I'm running about -2degree rear camber right now and about -3 degrees up front.

I'm looking at getting 17x8 rims, but I'm not sure what offset I need. How easy of a fit will this but? My rear fenders are currently rolled a little bit, but the front isn't. Will I need to do a bunch of rolling to run these tires?

Thanks!
Which Z3?

The inline 6 z3 (non-m) hubs on stock e30 trailing arms. I believe this adds about ~23mm to each side of the car but I'm not 100% sure on that number. Front suspension is e36m3 (coilovers).

I'm wondering if I can get away with et38 17x8 rims (back is rolled) or if it will stick out too far. What would the ideal rim offset be?

Thanks!

Yes, the non-M 6cyl Z3s had the long axles. 17x8 +38 should be perfect for your setup.

16x9
+25
Square setup, full size tires. Coilovers. I wouldn't mind running the dtm flares. Spacers are fine.
What is the best size tire I could stuff under it?

[drumad]

^you're going to need at least 13mm spacers up front in order to clear the strut tube

Offsets?

I've heard i need 195/50 front and 225/45 rear tires... correct?

I am looking at a set of wheels that are 17x7.5 et 20
however I believe they are for a nissan cause the center bore is 59mm.

Wheels are ATS Comp Lites.

Questions:
1. Can I get away with not running any sort of hubcentric spacer. The car has studs if that makes a difference.
2. Does anyone make a 59 to 57mm adapter?
3. My car is on Konis and GC coils. 550f/750r. I plan on using my current 16s for track wheels. What tire size for the 17s would be good for the street. I would prefer to run a 225/45 but I am not sure how that would fit. Tires are probably federal s595s as I have good experiance with them.

Thoughts?
