No Proper Size Tires?

[Mr. Wolfe]

The early models have a higher arch that can accommodate slightly more aggressive fitments. We're not talking about an insane difference, but if you roll the rear fenders, you can fit maybe another 10mm of tire.

I believe you're doing a full repaint, so NOW is the time to get REALLY aggressive. Remove the undercoating, and roll the rear fenders at the very least flat, pound the little bump in the wheel house flat, and go crazy. If you don't mind a mild pull on the rear fenders, do that as well. You might be able to future-proof yourself for even more bonkers rear fitments.

If I were you, who I am not, I would get 225/45R16 Direzza ZIIs all around. They're the proper size, ZIIs run wide, and won't look stretched. You have early arches which can take super aggressive fitments as well.

Thanks, those are the ones I was looking at. So the early models have a larger flare or larger radius arch? Is there a specific reason for that?

205/50/16 and 225/45/16 are close/bang on stock diameter.

Wider you could do 225/45/16 (or 225/50/16) + 245/45/16

225 in a performance street tire apparently stretches on a 9. My falken FK452's were square on an 8" in this size, but my Toyo TR1's look like slightly narrower.

245's are probably square on a 9, but I won't find out until my current rear tires are dead.

Both will be stretched, the front mildly, the rear just a bit more. If you just get 225/45/16 for the front and rear, you will only have stretched rear tires. If you're getting the 225 rear there's really no point in putting a 205 on an 16x8 when a 225 is available that fits. Yes it will look kinda maybe a bit off with the rear stretch but that's the what you get with a 16x9.

You can also get a 245/45r16 for the rear, which will only mildly stretched, it will just have to be a different tire than the front. If you're worried about rolling diameter - don't. We're talking 0.7" here, it doesn't matter.

Thanks for your input guys. Really appreciate it.

Sorry about all of the questions, but I really appreciate the help guys.

Please let me know your thoughts on this exact setup.

[Mr. Wolfe]

What I need is a 245/40/16 which NO ONE makes.

Mr. Wolfe

[TobyB]

There are plenty of proper tires for a 16x8 rim.

Im with you on that one!

:D

Its really hard to get an exact diameter staggered setup on an E30 ive found, thats why i went with square 16x8s. Any more wheel gets ridiculous anyway.

205-50s or 225-45s on 16s are about perfect for Daily/Autocross/etc

I am finding the same thing.

I always use this website. its not always exact, but its a pretty good estimate. just remember that each brand will stretch differently.

Thanks, I use that site as well.

That is a lot of stretch all around. If the widest tire you are going to run is 225 why not just go with a 16x8 square setup? 16x8 and 225 = no stretch. 16x8 ET20 square fits perfectly with fender lip rolling.

Also not sure how well 9.5" et2 will fit, that will stick out significantly more than my 8" ET20s, probably will need flares or pulled arches.

This site is pretty good as far as wheel fit sites go.

That exact setup I was asking about was referring to a set of Schmidt TH Lines that are currently for sale on the forum. I am trying to see if there is a way to make them work.

Here is what is important (to my problem), finding a tire size that keeps a close rolling diameter without an excessive amount of stretch. Keeping it inside the fender is a non-issue as I can widen the flares like such.

I am doing a full re-spray as well. If I cannot find a good way to use the aforementioned wheels, I will readjust my plans.

Could I get an opinion on this setup please? How much stretch would I have, etc.?

16x8.5 et12 with Dunlop 205/50/16
and
16x9.5 et2 with Dunlop 225/45/16 <--- This may be excessive

Thanks for all input.

I am one of the few that fall into a different camp. While some people (stance nation) see how far they can push stretch and camber, I like to see how far I can push the limits with VERY little camber, very little stretch, ZERO poke, and ZERO fender rub. I want to be able to "drive" the car, no doubt.
