New Tires for my SPF/427SB
 

I've had the BFG's, now running Yoko's, not very satisfied.
Present sizes are 255/60/15 and 275/60/15. Yes I like the look of 15" wheels.
Some vibrations and steering wheel shake, smooths out somewhat after driving about 15-20 miles.I've had 2-3 different types of balancing done with not a whole lot of improvement. I've also tried different tire pressures without getting much improvement.
Thinking of perhaps trying some Goodyear's or even going to the 15" Nitto NT555R's, I'm told Nitto makes excellent tires and they certainly look good. I beleive Nitto calls this a Street/Drag Radial, it is DOT approved, it's V rated which I beleive is good up 149mph. Nitto offers these in 275/60/15 or 275/50/15 which I beleive will work on the front, for the rear's they offer 325/50/15 also V rated. The Nitto's are relatively close to the tire O.D.'s I'm presently running and the width difference (OAW) are as follows: Fronts = +.625" (+.3125" per side) for the 275/60/15, and the Rears = +2" (1" per side) for the 325/50/15.
Haven't checked the prices yet, but it doesn't really matter (within reason) as I am really tired of fighting this issue.
Hopefully some of my fellow snake lovers out there can offer some thoughts on my ideas or perhaps suggest some other options?
I would really appreciate the help. I live in Arizona, so it's generally dry and sorta warm. Sincerely, Double T

Avons
 

You should consider the Avon CR6ZZs.

MT, Avon, Goodyear, Goodyear Billboards. Not too many choices. I've been really happy with Yokos so far, but I'll probably look at Avons down the road. You can search for tires on CC and find all kinds of opinions, but a limited number of options.

Go to 17" and you'll have some options.

If balancing the radials didn't get rid of most of the vibrations check your alignment.

I had a bad Yoko on my daily driver that had to be replaced. They could never balance and it pulled like a mother.

I suggest a 4-wheel alignment on a Hunter machine. Then a good wheel balance, also with a Hunter machine. (No, I don't work for them but am a big fan) My cars drive like a dream after doing both.

What Everyone Should Know About Wheel Alignment

Anyway, here's how the Nittos will look on 15s. They stick like glue, smooth as silk, but throw a lot of road debris and rocks under your fenders. If you get them, line the underside of your fenders with something like a dense foam hood liner material, or else you'll get spider cracks on your paint.
