[QUOTE="ITSTOCK, post: 15481454, member: 21353"] The sidewall helps, but if you are launching hard off a 2 step or a straight dump of the clutch, you still aren't going to save your half shafts and risk breakage. There is really no avoiding it. The bias ply tires with a sidewall will certainly extend the life of them, but there is no surefire way of saving the half shaft on a 3800 pound car launching hard at 4000+ rpm. I had about 20 3500+rpm 2 step 1.4-1.5 60' launches before I sheared off the outer part of the shaft (on a 4800rpm 2 step launch). The reason for 17x9 instead of 17x10.5 is simply because Hoosier does not recommend putting their 28x10x17 on that wide of a wheel. Either way, the bias ply (in 15/16/17) WILL eliminate the wheel hop which is the most common cause of half shaft failure. Don't launch quite as hard as some of us do, and you won't have a problem. The 28x10x17's wrinkle just fine, and while there will obviously be a little more flex on a 15, i doubt it's going to be a measurable difference when it comes to half shaft life. Getting a 15 to fit is a little different depending on the wheel, but they almost all will require substantial grinding of the lower tie rod, and some will also require grinding of the brake caliper and lower control arm. I did it on my previous Cobra and quite frankly, I was never exactly comfortable with how much material had to be taken off of the tie rod knuckle. [/QUOTE]
