From what ive read, offset "in wheels" comes in negative & positive. Positive offset means the rim goes more towards the car and Negative offset means the rim goes wider out the car. Am i missing anything here? Guys with the 2.5's, are lucky in a way because they get away with being able to run lower offsets on their wheels but are limited to four lugs. Us 3.2 drivers, have more options towards wheels but we can't run low offsets because of rubbing issues. It's nothing that fender cutting/ rolling wont cure, but in the long run will running lower offsets/ wider wheels on our TL 's cause suspension problems?. I've heard it can blow bearings earlier as well as mess up ball joints & things like that.

 

Offset is how far the hub area is from the center of the wheel. Then you've got the different discs that determine how far the spokes are from the hub area. Here's a diagram:

Also, considering we start off with a pretty damn high offset from the factory (+50), it's pretty hard to run low offset rims unless they're skinny as hell, and rolling is NOT going to enough to help. That's going into the realm of cutting and welding.

On this car, I've run wheels from +35 to +65 and 6.5" wide to 8" wide. All fit with no issues, but depending on tire selection, you might get a slight rub with the +35 8" if your shocks are worn.

have you had any mechanical problems when running wider wheels go90go?

 

Not at all. My front bearings went out because the car has almost 300,000 miles, haha. It's not like these Cubans I used to see all the time in Florida, whose 12" rims were 5" wide, and had the inner sidewall clearly visible. It looked like a retarded go-kart, haha.

So would a +35 offset on at 18x7.5 be flush with the fender or slightly tucked inside the fender. I'm trying to get as close to flush as possible without rolling the fenders. going with a 18x7.5 rim and 225/40/18 tires

You will rub in the rear...unless you are running some negative camber in which case you will wear your tires quicker. If you roll, but no camber you still might rub. I did on bumps during cornering on 225/45/18s, 18x7.5 and 45offset and a 3/4" drop.

 

actually TJ2.5TL and Monkey Butt:
i would actually consider using 215/40/18 with 18x7.5 rims instead just by personal choice. Also have u ever gave some thought to experiment with
225/40/18 with 18x8 rims? just curious.

 

Yes I've thought about it, and its a possibility I'm just looking for the perfect offset to where I can get as close to the fender as possible without having to roll them

 

well im running 245/40/18 with 18x8.5 with fenders rolled and no rubbing even with alot of weight but still stock height but really flushed

 

can you post of pics? what offset are you running on your wheels?

 

ill try wen i get it cleaned up, nd i think im either running et of 45 or 35 ill check tomorrow

 

215/40/18 will clear better, but be of smaller rolling circumference than stock.

If there was rubbing w/ 18x7.5" rims at 45offset w/ 225/40/18s, then using 18x8" rims will push the tire about 6mm more toward the fender. Were you curious to see how much more it would rub?

 

Since you are looking to get close to the fender for the 'look' it would probably be best to just commit to rolling your fenders. You can rent the tool online and do it yourself. The TL fenders are not difficult to do.

 

Sorry made a mistake on size of tire. Make that 225/40/18s. And to clarify the rubbing only happened w/ two people in the back on the outside rear tire on bumpy turns. I just really hate any kind of tire rub. Funny as my first modified car, a '76 Toy Corolla had wheels sticking out about an inch in the back. Car hardly ever rubbed 'cause I used traction bars on the leaf springs to keep the fenders off the tires, mostly.
