Full compression fender clearance?

blaiseam · Apr 5, 2020

I've been searching for an answer for a few days now and can't seem to find anything. I'm looking to upgrade wheels/tires and do not want to mess with suspension geometry from factory. Under full compression/tuck how much more clearance is there for wider wheels. I've used an offset calculator and the 2 options i'm considering add .7'' and .9" width to the outside with a 325/65r18 KO2. I would like to add a tiny bit of width if possible, but not at the expense of off-road capability.

Thanks!

Very little. They rub with stock everything.

I do know this, it may or not help you because I'm going through it. a 10" wide wheel with a 315 tire is fine a 12.5" wide wheel with a 315 has to have the front bumper spaced out for compression clearance and the rear section of the front wheel flare and wheel liner has to be fabricated, I am doing that this week. because my 12.5 tire will rub on wide turns. a 10" with -44 mm offset with stick out a tad bit, If you would like to see a picture my buddy has 10" wide -44mm 1 piece fuels. I have 12.5 -44mm 2 piece fuels. mine stick out much more.

Haha yikes, thats not much at all. I wonder if I can get away with .7" more. The wheels are 18x9.5 +20 with the 325/65r18 KO2's.

Do you know where you rub? Might it be the pinch welds?

He asked about full compression as pictured in the second post above. A 10" or 12.5" wide wheel will destroy the stock fenders at -44mm offset when he hits full compression. (Or any offset for that matter...)

It rubs in the middle of the fender wells about 10 and 2 if the top is 12. It’s not a pinch weld unfortunately. It’s the metal sheet. I try a take a picture for you later but it’s raining right now.

Oh damn. A picture would be great thanks. I guess i'd have to get some deavers and springs for perfect fitment, and I just dont think that'd be worth it.

So this was about 6 months ago from the pictures up top to these taken just now. I cleaned the inside so you can see it better. they are posted in a clockwise rotation from 9 to 2. Stock everything. Suspension, tires, pressures, and wheels

notice the "It may or may not help you" I was just letting him know what I am going through and what its doing with the offset I have with a 12.5 and a 10 wheel. I didn't know there was a right or wrong response. If it does help, great, If it doesn't then we all keep moving on with life, Its not the end of the world but thanks for letting me know what he was asking lol I appreciate it.

anyway @Donmatteo I hope you sort it out and get the answer your looking for bud.
Cheers!!
