is the a way of converting US tyre sizes in to i guess metric sizes? for example what do 7,5/100 R 16 roughly equate too.

thanks neil

thats not "american" thats "imperial"

Why what are you doing?
750r16 is std "old school" landrover size...

dont know many americans that work in metric, unless they work on europeian cars and bikes,

just a little planing on the doka, wheels, breaks, gearing, etc

OH DEAR!!!

But why have you got to "work in american"? Just coz they cant do "metrication" doesnt mean you have to copy them...

Is it a gearing calculator you are after.........?

This seems to work ok.. although I havent tested it against mine yet...

Yeah.. generally, most are running 215/75r15 for a reason.. (stock engines) its about as big as you can go without causing too much grief in the power department.. and without body mods...

Remember that blue doka at the spring syncro event last year??

errr not did not?

you may want to think about the tyre profile, there is no reason why a 16inch wheel and tyre combo, has to be any bigger (taller) which will affect the gearing than a 15 inch wheel tyre combo,

You are heading down a cul-de-sac ..... dont forget the ply rating necessary for a DoKa .......

Yes that is obvious, BUT even with the same rolling diameter 16" tyres are bigger tyre size than a 15" , no?

If your fitting ones with the same same rolling diameter why are you making your wheel arch bigger with the bits you picked up from that scrap van I take it you do know you will not have to do this.
