Thread: Tyre size equivalent

A Disco/Deefer steel 16" spare will only set you back $25 bucks or so on eBay. Surely that would cut out the guesswork?

(And by the way, the closest I could find was a 215r15, with a 5mm difference in diameter)

Here is one - works well Tyre Size Calculator @ ExplorOz Articles

And another Tire size calculator

try
Tire Size Calculator - Tire & Wheel Plus Sizing

If your spare is a stock disco 1 rim then it should be 16" x 7", the stock Tyre sizes for a disco are 205R16 (205/80R16) and 235/70R16, it sounds like you have defender tires fitted do you know what offset your wheels are? I think the standard offset is 33mm, it should be stamped on the wheel somewhere. There are numerous threads about Tyre sizes and the offset required to prevent scrubbing.

Oops typo the spare is a 16x7 with the tyre sizes you mentioned, the 4 wheels and tyres fitted are aftermarket alloys and Maxxis mudders, just wanna pop a trye on the spare the same rolling diamer. Ill check out theabove calculators

Thanks

Wouldn't it be logical to use the same size tyres...? Mums disco has 16x8's, mine has 16x7's and the trailer has 16x7's, all with 235/70-16's on them, they're all the same rolling diameter...

My RRC has 235/85's on it, good size tyres, chuck one on your spare, the rum width difference won't mean diddly squat.

I may have a new old stock General Grabber available for sale soon (came off a new defender in about '05).

Cheers
