General Alloy Wheel Sizes

[tezmc]

I'm after some alloys for my Bravo 80 SX. I know they need to be 4x98, but what wheel/tyre sizes can I get without making the speedo inaccurate?

Cheers

funny thing is almost every speedo reads 5mph too fast (use gps and check yours). usually sticking bigger tyres on actually makes the speedo more accurate.

How would I go about checking my speed with GPS? I've got a PDA with Tomtom and a bluetooth gps unit.

Any 15" wheels with 195/50R15 tyres seem to be a good compramise between style and practicality, at the same time being very good for cost.

use tomtom with no route set, it constantly displays your speed. on a motorway it is very accurate
