my wheel specs aren't really aggressive 9x19 offset 37 225/35 19 and still this happened when i hit a pothole:



this just sucks.. i thought with those specs i was safe.. how the **** could this happen.. the car is lowered to a "no gap" between tires and fender.

what can i do to avoid this, besides not driving through potholes? :F

 

I have this exact same spec. My tires are 235/35/19 Front and 255/35/19 Rear. Lower about 1.5 inches front and back. Front gets very very slight rubbing. Happens only when hitting extreme bump or running over big traffic bumpstop without slowing my car. 98% of the driving, no rub. The rear is ZERO rubbing. You can even go 265/30/19 in the rear without having to modify/roll/cut your rear fender. For the spacer, I have IS250 which has tiny front calipers. For IS350, if possible, you better try fitting it before buying the wheels.

 

Obviously, the answer is to raise the car up OR roll the fender out. You can't get away with "no gap" with the wheel spec that you have, even you consider it not aggressive but it is approx 1 inch poke out compared to factory wheel. This combined with "zero gap" shall result in bent fender for sure. I have 19x8.5 +35 with 235/35/19 running 1.5 finger gap up front and I have no problem at all. I guess 1 finger gap is about a border line of hit or no-hit on fender.

 

This will work with rolled fenders, pulled rears, relocated bumper tabs and you might need a camber kit. Tire sizing is perfect.

 

thanks for your answer.
i thought i am pretty safe, because here at CL are many car owners who lowered their cars much more then mine and have wider/pokier wheels.. so all those drivers have the risk to bend their fenders..?

another question, is it possible that better coilovers (i am on D2 coils) will avoid the tire meets fender situation?

 

Hi, Will 18x9 +37 offset with 245/40/18 tires (front) and 18x10 +44 offset with 275/35/18 tires (rear) cause rubbing issues? Lowered 1.5 inches. Thanks

 

2013 IS250 awd looking to put on the TSW Nurburgrings 19x8.5 45 offset in front in rear. Will 235 35 19 tire work?

 

You are not alone. They all have run into the situation over the course of their drives, sooner or later. Thread below can comfort you. Just read through, you will find some guys just repeatedly got the fender bended. They have learned to solve the problem by getting the fender rolled.

Other options you might look into:

1. Running stiffer spring. You don't need new coilover. Just change to stiffer spring (Higher spring's "K" constant). Those who have aggressive wheels and slamed ride height (tires tucked) run 12K or 14K on the front coilover.

2. Get the front camber arm kit. With more negative camber, you can reduce the risk of bending your fender. This is because the top of your wheel will slant into the wheel well, providing more clearance between tire and fender

3. Running smaller thinner tire. Such as 215/35/19

 

Ok I need advise on a very modest setup close to OEM spec. I do not want to lower my car or roll the insides of the fender , basically I do not want my wheels to rub at the same time want my ride to look a little better than OEM.

So I go to tirerack.com and choose the following tire size. Please advise if this will look ok and not create any problem for my ride or fenders.

2010 IS 300/250 OEM tires 225 / 45 / R17 front and 245 / 45 / R17 rear.

My question is ,on the same wheels can I mount 235 / 45 / R17 up front and 265 / 40 / R17 in the rear without doing any modifications or making it look odd ?

Is there any problem due the difference in AR between 45 and 40 from front and rear , will it look bad or spoil my ride quality ?

 

19x9.5 +22 fronts and 19x11 +22

rears are rolled slight pull.

looking for alittle bit of a stretch suggestions on tire sizes?

 

18x9.5 +15 front, 18x10.5 +15 rear

would this spec fits IS350 dropped 1.25in on Tein S.Tech? Also what tire size I need to run?

Thanks

 

2007 AWD not lowered ( yet)
19x8.5 offset 35
19x9.5 offset 38

Will this fit?

 

Well, I've been wheel shopping, so I thought I'd share my research. I took the factory wheels and recommended spacer sizes to come up with "proper" offsets. Then as wheel width increased, I adjusted the offset to compensate. For a wheel 1/2" (12.7mm) wider wheel, you would need half of that for offset, so add 6.35 mm for every 1/2" you increase the wheel width. Sorry it won't format right, but below is a little chart I made. The idea is based on a 12-15mm spacer being the right size for the front, and a 18-20mm spacer being right for the rear. With that in mind, these are the wheel widths and their offsets that should fit with no problem. I think the rear could probably be 5mm less offset to be a little more aggressive, but I think this chart is fairly safe. The top line is the stock front and stock rear 18s. So reading from left to right, you get wheel width, offset for that width, 18" tire size, tire revs per mile, 19" tire size, tire revs per mile, and the rim width recommended for those size tires. This chart is for properly fitted tires. If you want the stretched look, you can be more aggressive on your offsets, just do the math with the different tire widths.

9.5 42-47 285/30/18 790 275/35/19 783 9.0-11
10 49-51 285/35/18 804 295/30/19 799 10.0-11
275/30/19 813

 

Rawfish, based off my chart, the front is 1mm too aggressive, and the rear is 4mm too aggressive. That said, I think I have a 5mm cushion in the rear, so you should be fine there. As for the front, I read in another post that someone on BC coils caught their fender with the 8.5 35mm offset 235/35/19, but they were very low. You'd probably be fine at stock height to a moderate drop, but the possibility is there. If you run a stretched tire, you'd have nothing to worry about. And if you do any fender rolling, you'd have nothing to worry about.

 

Widest wheel/ tire set up front?
I would like to get 255 in a 9” wide wheel and +45 Offset Front and rear…anyone running something similar?

Thanks!
