Bbs ra 15x7 et 35 will they fit and look right? Also what's the best tire size to run.

They should have spacers ideally, 15mm front 20mm rear with 205/50 tires. But they will likely just clear the front struts without spacers depending on the tire used (but they will look very sunken inside the fenders).

I'm pulling the trigger on wheels tonight but just wanted a confirmation that I'm getting the right tire size. I ordering a set of TRMotorsports C1 in 15x8 and I'm thinking of the Yokohama S-Drives in 205/50R15. I'm on unknown lowering springs, prob Bav Auto ones and I can't roll the fenders. My car is an 87 so I have the higher rear arches. I'm not going for a stretched look, just want to find the squarest tire size that wont rub (if that makes any sense).

I would be eternally grateful for any feedback!

Sounds like a solid setup. 205/55 will look more square on the wheel and lead to a less-inaccurate speedometer though.

I just bought some BBS RS and was wondering...


2 wheels are already 16x9 +11
2 other wheels I will have resized. Would the 16x9 +11 work in the rear fine?

What should my resized wheels be to match the 16x9 +11s?



205/45/16 all the way around?
Or 215/40/16s?

Will this work??? (Fender rolling will be done of course...)

Help please!

Resizing 3pc wheels isn't necessarily that easy, what spec are the other two right now?

[Mystikal]

Front -- 17x8 +0
Rear -- 17x9 +0

Fenders are rolled flat and rear has a slight pull already. Both front and rear have aftermarket camber adjustments.

I was thinking 215/45/17 for the fronts and run a 225 or 235 rear? Thoughts?

195/45 and 215/40. Or 205/40 215/40. Either setup will require at least -3 camber front and rear. That's extremely aggressive.

Tire Size I would like to Run.

Front - 225/50R16
Rear - 245/45R16

What size 16 Rims do I need and what et?

Thanks
Anthony

Edit: Front and Rear Fender are Rolled Flush...

I always say 225/50 doesn't work up front, but if you're okay with the occasional scrub in the inner wheel well or on the top seam of the fender then they are "workable".

Ideal fronts: 16x7.5 +25 or 16x8 +22
Ideal rears: 16x8 +30 or 16x8.5 +26

Give or take a few mm of ET should be fine.

Thanks for the tip on the 55's. Tire rack is refusing to mount either sized tire/wheel combo which is a PITA but I'l see if I can go with the 55 locally.

Sounds like a solid setup. 205/55 will look more square on the wheel and lead to a less-inaccurate speedometer though.

Will I be able to fit 16x9 (6 7/16 backspace)? on front and rear with 18mm adpaters. if so what tires?


I am sitting on kw 60mm/40mm springs with no spring pads.

Resizing 3pc wheels isn't necessarily that easy, what spec are the other two right now?

They are 16x8 +33. I have a place that have already resized the 16x9 (before they were 7" wide with a +33).

So at the moment I have

16x8 +33
16x9 +11


So by resizing the 8" wide wheels, what should I resize them to to match the 16x9s? And tire sizes? Thanks!

That's a +30 offset. With 18mm adapters that is dead-on ideal. 205/45 is my suggestion.

Yup.

I see. Did they just change the outer lips or the inner barrels also? If only the outers the new wheels are actually 16x9 +8.

Suggestion 1: Keep them 16x8 and run 20mm spacers.
Suggestion 2: Change only the outer lips to 1" wider netting a 16x9 +20 wheel. Run these on the front with a 10mm spacer to clear the struts.
Suggestion 3: Go all out with the resizing and make them 16x8.5 +10 to +15.

What tire size should I get? Could I run 16x9 up front?

[Mastrcruse]

The e30 I just bout has oem basket weaves and is need of new tires. There seems to b VERY few options. I can do the oem 195/65 or 205/60? Looks as if the falken 512 is the best option out of the 3. Need something good in rain and don't need anything crazy expensive...just something that'll hold me over while I go thou the refresh phase of the car.

Any other suggestions?
