Post Couple of wheel questions...what fits? offset?

After heading out to grab a car cover (my garage space is now taken up by a 2000 silver Land Rover...I told my mom that if she really wanted a Rover she could've bought the company, heck, I could've bought the company ) I decided to do a little window shopping.

First I went to the muffler/exhaust specialist, who said it would cost $85 for custom tubing. Solid, I think, and if I only pay $99 for the muffler and $30 for a tip then I'm set. Borla tips are $60+...any reccomendations for good tips out there? I don't feel like mixing/matching brands, so generic is fine, but I'm mainly interested in size...what length looks best?

Okay...now back to the topic. I then head to one of the local wheel/tire shops, which has tons of nice (?) chrome wheels, but does carry quality brands like MOMO and TSW and BBS and so on.

What I want to know is the proper offset for our wheels...someone said 50mm (!) but apparently only the Jeep Cherokee uses that. The guy said 42-44mm. Sound right?

And what's the best size wheel to use...16 by 7 is stock, but will 16 by 7.5 fit? How about 17 by 7 or 17 by 17.5? Maybe even 15s?

As for the tires...he quoted T-1s as $25 more than Mike Shields. If I get tires I think I'm going to get them from tire rack.

Speaking of Tire Rack, anyone have any experience with their wheels? The Team Locos look okay but I haven't heard much good about that brand. And the SSRs are expensive!

Thanks for the help. After I handle the exhaust tires will be next...I can feel the meagre tread eroding. I think some of the powersliding on dirt did that.

I am quite sure the factory wheels have a
53mm offset. Most others that fit well are
50mm. There are a some 48mm wheels that fit.
Anything less will be likely to rub.

I believe that 15x7, 16x7, & 17x7 are the
proper widths to go with.

Tires should be 205 or 215 sizes, although
some have said 225's don't rub the strut or
fender.

I hope this helps.

48mm MINIMUM! There aren't all that many wheels that will fit the Sube and the subject has been debated to death. Do a search and you'll get a ton of info. 16x7 is stock and some have run 225/45s and report no rubbing while others run 215 and report rub...go figure. We KNOW that 205/50/16 is OEM WRX size and that Prodrive likes a 17x7 rim with a 215/45/17 tire... I heard Tire Rack's Team Locos will rub they have a 45-48mm Toyota offset. Tire Rack still has 1998 RS (gold - 16") alloy take-offs for $109 each. Many go that route for a racing set. (Why go with a larger, heavier wheel and tire for racing!) You know, the 2000 RS rims are super light and are hard to beat (check out Rays Volk TE37s for comparable weight major $$$$) so the best solution seems to be to save your money for good tires and mods that will actually do some good performance-wise. DEFINITELY get a bigger rear anti-sway bar. Have fun.

Thanks for the help, Nightmare and Joe.

My real question lies not within the "confirmed" tire range...the obvious stuff (ie losing an inch off of diameter, etc.) but whether anyone has attempted to use a slightly odd wheel size or something other than the standard Raceline/Speedline/Volk/Advan stuff that we always read about.

Fortunately, I don't need a racing set, but I don't want "clunkers". I'd just like something different, something that looks a little better than stock.

I have a 99, BTW. And I am planning on getting tires with the wheels...looking at Dunlop 8000s right now in terms of tires.

I already have a sway bar, and this tires/wheels thing is a long way off...I just wanted to know if anyone had some answers for me. It helps quell the immense want I am feeling for new car stuff.

I have a set of TE-37 17x7.5 inch rims with +48mm offset. My tires are Kuhmo 712 ECSTA(rated at traction AA, temp A) at 215/40.

Stock suspensions. I doubt even if they were lowered by an inch, there would be no rubbing.

16x7 or 17x7
18x7 = need to roll fenders
48-53mm offset
45mm can work but sketchy
5x100 bolt pattern
225 on 53mm 16's ok
215 on 48-53mm 17" ok

clear and simple, hope it helps

Is this wheel questions as opposed to pwetend ones?

OK...I'm playing "devil's advocate." **flame suit on**

I recently put Enkei Etorias on my '98 OBS. As you all may know by now, Enkei makes the OEM alloy wheels for Outbacks and Outback Sports (not sure about RSs), so they know Subarus.

Well, when I purchased these Enkeis, their fit guide said that my car (with 15" wheels) takes a +38 to +45 offset. I was like whoa...SOA told me my steel wheels had an offset of +55. So, the wheel guy showed me that Subaru measures offsets differently than aftermarket wheel manufacturers. Subaru measures from the absolute outer edge of the rim. Most aftermarket manufacturers measure from the "bead" where the tire meets the inside of the wheel. This makes a HUGE difference! So, we measured my steel wheels and then measured the Enkeis (which were listed as +40 offset) the way Subaru measures offsets. Well, as Subaru said, my steel wheels had an offset of +55. Then we measured the Enkeis and found out that instead of being +40 they were actually +48 when measured the way Subaru measures offsets.

My advice...don't throw out any wheel options until you have measured them yourself. You will be surprised.

I love my wheels and I only paid $65 each for them.

Now that we go in to the wheel debate once again, I want this question answered.. (hopefully)..

If I put 17x7 TE-37's with 50mm offset (or 48mm like Snoopys) would I have to recalibrate the speedo at all? If so, how do you do it?

I didn't. The diameter I have now is slightly less than the stock diameter(with stock tires and rims) the speedo was calibrated to. The speed difference is minute. I need to find the formula to find the percentage difference.

Samurai :

to get the diameter of our stock tires/rims 205/55 16

(205*.55)2 + 16(25.4) = 631.9mm diameter

(The 25.4 is to convert inches to mm)

To get as close to our diameter(to avoid inaccurate speedo) I chose 215/45 17

(215*.45)2 + 17(25.4) = 625.3mm diameter

That's about a 1% difference from stock diameter. When you read your speedometer, just subtract 1% and you'll have your corrected speed(if you get 215/45 on 17inch rims).
