Hey everybody,
Continuing to make headway on my new Pathy but ran into a bit of a stumble this weekend. Yesterday I had a new set of wheels and tires mounted up and installed. The specs:
Tire: BFGoodrich All-Terrain TA/KO, 31 x 10.5 x 15
Wheel: Cragar V-5, 15x8, 3.75 in backspace
Immediately upon entering the freeway onramp I felt a very noticable wobble in the wheel - I was tempted to just turn around and have them re-balanced but due to my schedule I decided to bring it back later, (Discount Tire - lifetime re-balances,) however I've since driven the truck a couple more times and I don't believe it is actually a balance problem as it's very inconsistent - at the exact same speed sometimes it's VERY noticeable and sometimes non-existent. I should note here that with the stock wheels and tires (265s) there was no vibration whatsoever at any speed.
The tension rod bushings look a little dry, but solid. I'll probably throw on a set anyway as a maintenance item but not convinced at all that's the source of the problem. My biggest worry is actually that it's the wheels themselves as they are lug-centric, but I've run the same wheels on other cars and trucks with no vibration problems whatsover - are Pathys especially sensitive to this? Seems like plenty of folks run similar Cragar steelies so I figured they were fine.
Anything else that's a likely culprit?
