Wheels are getting difficult to find in the 13" sizes.
I'm trying to find a reasonable increase (+1) without affecting acceleration. From what I've read the more weight on the tire& wheel combo. The slower it will accelerate the mass (equal to a heaver flywheel). In essence it eats torque/horsepower. It also affects economy (thought this is not a primary concern).
I want to keep the unsprung weight to a minimum. On my motorcycle the affects of this are very obvious. I'm thinking that the concept also applies to a 1200, but to a lesser extent.
My questions... I found a 13x5 alloy wheel with a +30 offset. Per the Tech Wiki the stock 12x4 steel wheel also has a +30 offset. Would it be correct to conclude that his wheel will fit? From a clearance standpoint, would this result in adding 1/2" to both the inside and outside of the stock wheel?
Though the wheels are new, they are not returnable. So I want to get it right the first time.
BTW... I plan on using 185/60-13 tires. These appear to be a very close match to the overall size of the 155/80-12. Does anyone have tire recommendations in this size?
Thanks
