Looks good! Any difference in ride or handling?

Well, I have an issue with this setup. At full steering lock the outside edge of the tire impacts the fender liners. It rubs the liner both front and rear.

What's tire size you running? It may be too wide.

Outrage

245/40 R 19 at all corners.

Thanks for posting your results.

I assume you meant rubbing both front and rear of the front liners, right? I don't think your car is low enough to get any rubbing on the rear liner.

I guess that is .5" wider wheel than stock and 10mm wider tire than stock. Are they willing to switch your wheels to +42mm offset?

Outrage

The tires are rubbing on the front fender liners, forward and rear, as you stated.

I called RavSpec concerning this. The recommendation is that I switch to a lower profile tire (35 series). That's all well and good, but I already own a set of 245/40 R 19 tires, so it's not overly helpful.

Sorry to hear.

Your Work 19x8.5 +35 sticks out 13mm (from stock f sport 19x8 +42) and it rubs at stock height. Hard to believe this car has so little tolerance on the outside part of wheel.

Yet only half the people running Vossen 20x10.5 +45 rubs and that setup sticks out 34mm (from oem f sport 19x9 +60).

Maybe manufacture stated offset varies that widely from one to another? Either that or verify that they sent you the correct offsets.

I'm running 235/40R19 +40 offset and have no rubs. There about an inch left between the tire and fender liners at full steering lock with 235 tires. Look like you have to swap to 235 tires?

Hey man looks great !!!

The names Paul and i am the local Rep with Need 4 Speed Motors.

I like how the wheels are simple and clean fits well with the body lines of the car

You should look into lowering it with the Tanabe NF210 springs

itll lower the car 1.1" on the front and 1.2" on the rear which will give it that nice low look without worrying about any rubbing and or driving clearance issues.

Well, it seems as though the rubbing stopped after a day or so driving. I tested for impact by driving in circles at full lock, in both directions, forward and reverse. I had my wife listen for rubbing from the outside of the vehicle. After a few rotations, any rubbing ceased. I inspected the liner afterwards. Any rubbing of the fender liner was light, very light. It was not sufficient to significantly wear down the liner to any degree. I believe the inference was on the magnitude of fractions of a millimeter.

A couple of reasons could explain why some experience rubbing and other don't. The rim's width versus the mounted tire's width will affect the overall diameter of the tire. Stretching the tire's sidewalls outward will move the tread closer to the wheel's rim. I'm using a 8.5" rim, which is which is the reference width for most 245 mm width tires. My sidewalls are rather perpendicular to the tread. On a 9.5" rim, the sidewalls would have an obtuse angle to the tread. Secondly, some tires are larger than others. The edge of the tread on my Michelin Pilot Sport A/S Plus tires is larger than most tires on the market. I believe this is done to offer more tread surface for a given tire width.

In any case, Toyota did not design much, if any, additional room within the fender for non-standard-sized tires. This likely explains why oddball 235/40 R 19 tires were used on the F Sport models.

235/40/19 tire to a 245/40/19 tire is not a huge difference on a 8.5" rim.

the stretching on that tire spec is so slight that you cant really notice it unless your trying to look for it.

A 235/40/19 to a 245/40/19 on a 9.5" rim you will see the stretch more obviously then on a 8.5" rim.

But even at that it is nothing that could cause damage to the lip of you rim or impact your driving abilities.

Toyota did not base this model on the ability to modify it.

But it is capable of being done here is a perfect example.

4th generation GS vehicles have been setup with Vossen wheels in 20" staggered

20x9 & 20x10.5

Here is the thing when you go to that sizing the tire specs are adjusted accordingly.

thinner tire profile allows the wheels to clear the fenders correctly. so for that type of setup it would be a

245/35/20 tire and a 275/30/20 tire.

with the thinner tire profile it allows for the wheels to clear the inner fender without rubbing when the vehicles suspension is moving up and down.

Outrage

A 245/35 R 20 tire is just a hair larger (1 mm) in overall diameter than a 245/40 R 19 tire.

Need4Speed

You are correct!!

the 245/35/20 has a overall diameter of 26.8"
the 245/40/19 has a overall diameter of 26.7"

I don't think the OD of the tire is the issue. What's causing the problem in this case is the rim/tire width and offset. Especially when considering interference during steering lock to lock.
