Default 17x8.5 +48 and 245/40/17 - Possible rubbing?

Looking to get 17x8.5 Advan RS or RCII with 245/40/17 for tires since it's pretty close to overall diameter with stock sizes (205/55/16) according to 1010tires.com's Tire Calculator.

I'm currently sitting on H-Techs with Tokico D-Specs but I may be going with RCE Yellows soon. I have about -0.6* of camber up front and -1.8* in the rear. Alignment can always be changed some time next spring though.

So what would I have to do to avoid rubbing in this scenario? I would rather stay away from rolling my fenders but if it's the only way then I might try that.

hmm.. do you do any competition with your car?? i'd personally suggest changing your camber anyway.. -.6 up front isn't really a lot and -1.8 is kinda too much.. so in a nut shell, yes there is the possibly of rubbing

My gut says yes, but how depends upon the wheel offset.

Thanks for the links labcoat, I did see the 3rd one before but yeah. I'm just asking simply because there are left over stock on those rims and I would have ideally liked to go 17x7.5 and 225/45/17 but then it would be special order.

I was wondering if I could have got away with this width and size. If it helps, I never really carry more than 1 passenger at a time and nor do I load the trunk with anything heavy. Although I do like to corner hard.

Back Road Runner, the wheel offset is +45 or +48mm depending on which wheel I go with.

235/45/17 is actually a larger size than 245/40/17 too but did you actually rub prior to rolling them or just to be on the safe side?

I guess I would just be worried about the width right? Depending on the alignment and drop, I could rub either the strut or the fender. I guess it's only the rears that would rub the fender and the front could possibly make contact when the wheel is fully locked?

depends on the offset.

for example I rubbed with 17x8 +48 and a 245/40 tire but I only run a half degree of camber out back. If I had 1.5* it probably would have cleared.

I would say if they are a high 40 offset and you still have the 1.8* camber in the rear you should clear them. But that all depends on the offset.

I agree though I would raise the camber up front to a full degree and lessen the rear a bit.

i think it may rub...i have 18x8's +48 running 235/40R18 (star specs= wide), -1.8 camber and during full compression in the rear, there is about enough clearance between the sidewall and fender lip for a couple sheets of paper hahah...it's close, very close

+45mm will give you a little wiggle room to play with camber if you want. +48 is what I have and am around 1/8" from the strut, but there is some wiggle room in the bolts too. This is on a Forester, so I can't comment on the fender. You'll most likely need them rolled some. +48mm is dead center on the Forester in the wheel area, but I don't know about sedans. As well, it doesn't leave much extra room so a wide 245 or one on a wider rim could still rub. I'm on a narrow 7.5" rim, so my section width is 9.6" On an 8.5" wide tire you might be at 10". Well, there's your 1/8" gone and you're up against the strut shaft. Pulling the hub out as you tighten the main strut bolts will give you more room without stepping to camber bolts, but you're not getting a ton, and you're still shoving the tire out to the fender. 245 wide tires walk a fine line.

Damnit...it's starting to look like my 17x8.5 option is starting to look worse. I will probably have to go with a custom order for those Advans since 7.5 wasn't that common.

I have Advan RCII 17x8.5 +45 w/ Dunlop Direzza Sport Z1 Star Spec 235/40-17 on SPT Pink & stock shock w/ slightly rolled rear fenders, -1.5* camber all 4 corners... no rubbing.

I used to run Bridgestone Potenza S-03 PP 245/40-17 (which was only slightly wider or even similar in width to Star Spec in 235/40)... rubbed on rear fenders on super sharp corner (e.g. 180* turn freeway entrance ramp) when I pushed hard but ok when I took it slightly easy. No rubbing in front at all.

If your car is a sedan, I wouldn't worry too much about about it. Remember... these Advan RCII were made for our car specifically.

So only on hard corners you rubbed the rear? Hmm...maybe there is hope after all. Maybe some stiffer springs and stiffer dampening could be the answer?

What brand & model tires are you planning to put on? Some tires are wider than others... especially Dunlop Direzza Sport Z1 Star Spec, that's why I chose 235/40 instead of 245/40 (cheaper too ). The speedometer difference is less than 3% so it should be ok. Plus, it should better gearing for if you track the car. Even Bridgestone Potenza S-03 PP was supposed to be one of wider tires back in the days, so it really depends your tires choice as well.

This is slightly different than what you are doing, but I am using 17x8 +45 with 245/35R17 Toyo R1R, it fits just fine... my camber is from my camber plates, not the bolts. BUT the tire is too short now, I should have used 40 series... but the 35 is good for accel.

I was going to get another set of Falken FK-452 but I may just try out the new Goodyear Eagles and see how I like them. It would just be for spirited daily driving.

littlewhitewagon, didn't you experience every little imperfection on the road just that much more with a 35 profile? lol I would like to get as much sidewall as I can just for comfort which is why I would have either went with 225/45 or 245/40 depending on if I can get 17x7.5 or 17x8.5 wheels.

Some 245s are wide, some narrow. It also all depends on how you place the tire between the strut body and fender with camber settings. All I can say is it'll be a tight squeeze. When I first went to 245, I didn't know if it was going to fit. Sitting off the rim in the garage, they sat at +10" width, too much to fit. Once on the rim, they went down to 9.6" for section width on my 7.5" rim. It might be around 10" on a 8.5" rim though. That'll put it right next to the strut body. Depending on how wide the tread is, it may rub the fender too. It's sort of a matter of which tires you pic, and test fitting them to see if you can squeeze them in.

Yes, and no. Yes, I feel lots of bumps... but that is more from my suspension choices than the 35 series sidewall. In comparison, my 235/40r17 r888 is not much better than the 245/35r17 r1r. However, I am now more afraid of denting or bending a wheel.

I think I'm going to put my 18" Volk CE28 back on for the street since a forged wheel should be stronger than my RPF1s...besides, winter (rain) is coming.
