Re: The dreaded drag radial wobble
 

I would not like to go there for a number of reasons :
1. It was not my problem so I never heard it from the chassie builder myself

2, Since it was not my car I was not interested enough to maybe remember what I heard correctly if what I heard now was correct!

3. This was in the beginning of wider Radials so "the problem" has most likely moved around between brands since then with moving factory's and outsourcing etc.
also it could have to do with what car or combination you have?
only a reputable chassie builder would probably gathered enough info to know about this.

Free info is what all expect and often get on the internet, and it's usually worth what you pay = nothing:D

Well Ok...here's the free advice : If I remember it correctly I think he was told to get Mickey's :rolleyes:

Talked to the Goodyear representative and he said to raise the front tire pressure to 40psi and try that.

And does Mickey Thompson even make a 14” wide radial?

Re: The dreaded drag radial wobble
 

I am not a radial expert but I have worn out a few sets of similar sized Hoosier radials. I will offer what I do and don't do. I only have about 600 hp first of all. I think radials are more sensitive to track temp and prep. I never run more than 13 lbs of air, at 18lbs the outside 2 inches of tread doesn't contact the track. Maybe you are running about 5 or 6 lbs too much air pressure ,that's a lot. I have a four link , no anti roll bar, bias ply front tires and I routinely switch from radials to bias ply with basically no change other than air pressure. I would consider where your four link is also ,perhaps shorten it up some so it keeps the tire planted and a shorter setting has more triangulation and thus less roll tendency. I believe that as the tire unloads and slips is when this problem happens. Most of the cars with lots of gear and weight transfer seem to work fine. Good luck!
