Diamondback/Michelin X goldline 205/75R15 tires

[Glen C.]

I've ordered a set of Diamondback tires. After installation I will have a full front & rear wheel alignment & balance performed. For regular driving should I deviate from the GM 775/15 bias ply tire recommended alignment specs, to accomodate the new radial tires? If so what caster, camber, & toe in, specs would you recommened?

Glen,

From Duke Williams:

Touring w/ radial tires
Front:
0 deg. camber
+1.5 deg caster (+2.0 w/pwr steering)
1/32" toe-in per wheel

Rear
-0.5 deg. rear camber
1/32" toe-in per wheel

Sport w/radial tires
Front:
as much negative camber as can be achieved up to -1.0 deg.
maximum positive caster that can be achieved
1/32" toe-in per wheel

Rear
-1.0 deg. rear camber
1/32" toe-in per wheel

All cross readings should be as close to zero as possible; 1/32" toe-in per wheel is equivalent to 0.133 deg. toe-in per wheel with 27" diameter tires.


I hope this helps.

When I ordered and installed my Diamondback redline MichelinX tires on my '67, I didn't change anything in the alignment from the 7.75X15 bias I was running. I have had it on many long trips at 70-75 mph and on twisty mountain roads and it handles and rides great, so much better than those bias ply things.
