Roush Iridium Gray 17x8.5 +25 offset

How long did you have the lift before the wheels and tires? Did the vibration start only after the wheel/tire install? A high speed vibration is generally tire balance. Roadforce balance will help determine if the tires are out of round. Any tire shop should be able to warranty the tires through Nitto. Do you have a Discount Tire near you? They are great.

I did the lift At the same time and Don’t think I had the old wheels on a day before I got the new ones done… Roadforce that’s the balance the second shop did and they suggested the tires may be out of balance but of course since I didn’t get the tires there they were not willing to deal with the hassle.

Discount Tire might be willing to help, if you have one local.

Road force balancing will tell you if a tire is out of spec. Unfortunately. I think a lot of shops say they road force balance, but they really don’t.

Sorry to hear you are having vibration issues. Your local Discount Tire location may be able to identify where your vibration is coming from. If I can assist with this please reach out. We'd love to help!

So I tried airing down my tires to 35 and that greatly helped. But some quick driving and the tires heated up, pressure back to 37 or so and some of the vibration came back. I’m now going to try rotating one side at a time to identify if it was a rear or front wheel causing the issue. It seems to be coming from right rear…
Using this site to calculate new pressure and I’m coming up with 35psi https://tiresize.com/pressure-calculator/

I was originally running 40-42psi when these were first mounted.

Tire pressure should be set at a “cold” pressure. Once you drive, that will change a couple psi. Don’t worry about 35 jumping to 37. I run 35 in mine. Anything more and I can feel my kidney being relocated.

 

[watersniper]

For sure - will need to re-set the tire pressure later tonight once she cools off. It’s so much better already, running at the lower pressure!

After many rabbit holes, these are now my favorite. Should look great with the new Ford Racing/Warn bumper and 2.5 Fox parts sitting in the shop.

Especially as they are NOT black and no ridiculous offset. I know I am resurrecting an old thread but curious if the OP got the vibe issue fixed?

 

[watersniper]

Everything has been running great ever since I dropped the cold pressure to 35 psi no more issues after that! I have had really good luck with these and they are holding up nice. Recon Grapplers have been nice. Probably 2 to 3 mpg drop in fuel economy overall.

Wonder how they would look on cactus grey.

 

[watersniper]

I think it would be awesome on Cactus Gray!

 

[pismo1]

Would 265/70-17 tires look good with these wheels or are the wheels to wide for that size tire?Also do the STX wheel tpms work on these wheels?

 

[Superspirit]

Seller will not budge on price now. I tried.

 

[Superspirit]

Well, I tried for a week and the guy wouldn't budge. So I finally gave in and paid full price for a set.

Now to decide on tires. I have a 1.8 lift in the front, row springs in the rear, not sure how big I can go.
