spare tire?

[bryanf89]

i want to get a donut style spare tire for my 89 supra to replace the stock heavy one. i found a tire for a 2003 and up corolla that has the 5 bolt pattern. will this work, if not, what will?

What are the dimensions and offset and what is the load limit? You'll need to make sure it'll clear both the front and rear brakes.

Unless it is a 16" rim, it will not clear the front calipers. I tried to put some donuts on a parts car for it's last trip to the salvage yard, and a 16" donut with minimual offset managed to fit. A 15" or smaller didn't clear the brake caliper. I managed to fit that one 15" on the rear, tho.

BTW, I hate those donuts. They will limit your car by speed and agility, and it flat out sucks to have to drive 50 mph on the interstate with trucks blowing by at 70. Trust me, it only happened once with me, and I'll never do it again. Every car I bought after that with a donut got a full sized spare immediately.

Sometime 16"s don't even fit (they hit the outer face of the caliper)... If possible it would be best to try to arrange a time to test fit them.

To be honest, the only reason you could have for wanting a donut spare is for weight saving right? I certainly hope you ain't going on looks!

Anyway, for the amount of weight you'll save over a full sized alloy wheel & the limitations (some would say danger) caused by the narrow tyre style, I'd say you'd be much better off just carrying 2 or 3 cans of tyre foam (it's called tyreweld here in the UK, think it's fix-a-flat in the US?) and/or a footpump.

At the end of the day, unless you're really unlucky you're not going to have more than say 1 or 2 flats every couple of years & most times just pumping them up will get you to a garage. It's up to you really, but I'd say either stick with a "proper" spare or if weight's that much of an issue don't have one at all.

EDIT-: if you wanted I suppose you could offset the weight of a proper spare by running only enough fuel in the tank for the journey you're doing, after all if you're concerned about a few lbs you're more likely doing short runs round a track or strip rather than the daily commute I'd guess...

Yea your right i wont sacrifice safety for only a lil bit. Ill focus on power first and weight as my second priority

i seem a carbon fiber hatch if i get that along with a CF hood wud the weight distrubition be right? Would it be too light?
