It sure would. I would guess there is probably as much as 10% to be gained
by having a bigger tire diameter. But most of the larger tires are bias ply,
and I think I'd stick to my Dunlop SP20 radials (165SR15). There was
recently an article in MGA magazine on that very subject, but a lot of those
tires are pretty pricey - Dunlop SP20s are about $50 per tire here in
Minnesnowta.
I have opted for the 4.55 conversion as I am a bit more concerned about hill
climbing ability than all out speed. I'm only looking to drop about 500 RPMs
at any given speed. The 4.55, I figure, will do that nicely.
