I snapped a few. Sorry, but my wife's Forester was parked right next to mine so I had to use a wide angle 10-20 lens to get the whole car in the shot. But you get the idea.

I hope your 235/50-17's are smaller than these Michelins. It was a little work to get them to not rub. I rolled front and rear fenders. Also I'm running 1/4 spacers in the rear.

Thanks! What width/offset are the wheels?

I was running P225/55-17 Advan S4s on the OEM 17 X 7 wheels with plenty of room to the strut in the rear - it looks like I have a little better than 1/4" clearance from the sidewall to the strut.

The section width of the P225/55-17 Advan S4s is 9.1" on a 7" wheel so I should be able fit up to a 9.6" section width.

The section width of the Bridgestone P235/50-17 RE960AS is 9.5" on a 7.5" wheel. These tires will be going on 17 X 7.5 Rotas.

I guess I'll find out soon enough if my calculations are correct!

My wheels are 7.5" / 50 mm. I'm running 3 mm spacers in the front for clearance with GR-2 struts. The section width for these Michelins on 7.5" rim is 9.6" and they are tall at 26.6". I measured them and I got 247 mm for width and I suspect they may be even taller than the official spec say too.

I'm on Forester GR2s and Whiteline Control springs, but I think it's about the same drop (or close to it) as the Swifts.

235/50/17 Yokohama S.4 on 17x8 +48 offset Rota Torques. I have 5mm spacers in the rear (probably could have gotten by with 3mm, but it would have been close).

Not what I want to read. I have a set of 235/50 Blizzaks waiting to go on. Just have to decide if they are going to go on BBS's (17x7.5 et53) or RS-Zero's (17x7.5 et 48). Looks like I may have to go with the Zero's.

Yep, the SF. Already have some minor plans for the car, brakes, suspension, exhaust and intake and wheels tires. Some of the stuff I have left from the FSTi will work on the SF (FSTi suspension, wheels/tires). Have an intake for it already, working on exhaust.

Ah, right. Forgot you had the SF as well.

Your car looks great! I am actually looking at going with the Advan S4s again in P235/50-17, but I think I'll be OK with the 17 X 7.5 Tarmac 2s. Here's why...

After some exhaustive research on this site - especially in the Tire size / Wheel size / Offset /etc...log (will it fit?) thread, I have come to the following conclusions:

1. On a wheel with an ET48, a 9.6 inch tire cross section just clears the rear strut with no room to spare at the typical - 1.2 to -1.5 camber we usually end up with.

2. According to Tirerack, the P235/50-17 Advan S4 has a cross section of 9.5 inches on a 7.5 inch wide wheel.

3. On the Michelin site, they state that every .5 inch change in wheel width from the "measured wheel width" spec results in a .2" change in cross section.

4. In your case, the use of the 17 X 8 wheel added .2" to the cross section, resulting in a final cross section of 9.7 inches for that tire. I would have guessed that combo would not clear.

In my case, I'm sticking with the 7.5 inch wheel so according to my highly scientific research and analysis ( :icon_rolleyes: ), I should be good to go without spacers.

I guess I'll find out in a few weeks.

Thanks for the compliment!

I remember looking at the spreadsheet in that thread before I bought the tires and saw a few others running 235/50/17 with no spacers and no rubbing. Based on that I thought I would be OK, I didn't think about how the extra half inch of rim width would come into play. Truth be told I would have just as soon gone with a 7.5 inch rim, but I was able to pick these up here on the board for a steal.

I was running swifts with yoko s-drives 235/50/17 mounted to tarmac IIs. I had to run a 3mm spacer in the rear. I was able to run 215/60/17 with only minor rubbing in the fender in the rear.

Sounds right. The Yoko S-Drive in that size is listed as a 9.7" cross section on a 7.5" wheel. I'd like to go with the Pilot Sport A/S in that size but that too is listed as 9.7 inches on a 7.5.

In P235/50-17, the 960 A/S Bridgestone and Advan S4 are both listed as having a 9.5" cross section on a 7.5" wheel.

Based on your math above, the 9.5 section width of the LM-22 on the 7.5" wide wheel SHOULD fit. Still think I'll run the et48 wheels over the et53 wheels, just to be safe.

I think you will need the ET48 to avoid spacers.

My Advan S4s in P235/50-17 and Tarmac 2s are on the way. I will post my results here.

Keep in mind the sub-zeros dont clear brembos...dunno if that is your plan tho.

My T2's are fairly close in the rear w/ re-01r 225x45, but I think there will be room for a 235.

Looking at the 235/50 combo on Rotas;
would the 17x7.5 ET45 give the space needed to run S.Drive/PilotAS/Proxes4?

I am considering the SDR/Torque/T2s and they are all listed with this offset as well as the ET48..
