One tire took 1/2 oz total to balance. The other tire takes 3.5 oz in one area. Pulled tire off and checked the wheel balance and it is perfect. Checked this on 2 spin machines and even stuck it on my old bubble balancer. Tire runout is fine. Has a high speed shake like an out of balance tire. It spins up 0 with 3.5 oz of weight on it but its a big hunk of lead in one spot. No warranty because they have a couple years on them building the car. Should I make a tire swing out of it?

try breaking it down and rotate the tire into a different position

tried 1/2 a turn on the rim no change.

change it to the other rim , rotate if needed!

also , be carefull that the center is not 'running lose '

Flip the tire over.Had some at work that took lots of weight.Sometimes flipping them over will work.Same with rotating them Ive had to rotate some 3 or 4 times.Sometime you just get a tire that takes weight.Rocky

I think it is MT for some reason. I just bought 4 of their tires for my street rod and they took a ton of weight on new rims.

I went ahead and ordered another tire. 3.5 oz on such a small tire on a 3.5 rim was a big chunk of lead.

Any chance of getting it balanced on the car? Probally to late now, sorry.
