Using Mag Wheels Question??
 

Ive just bought a pair of Mag Marchesinis for my track bike, which is a 748R running 853 and gasflowed. I have always run with a 180 rear tyre on my original 5 spokes, but i believe when i pick the mags up they will be a 6 inch rear. Has anybody any experience using a 180 tyre on a 6 inch rear. Or if using a 190 i take it there shouldnt be any clearance or handling issues??

Some tire profiles are more sensitive to rim width than others. Dunlop, for example, says that their 180 slick works fine with a 6.0 to 6.25 inch wide rim. In the past, both Michelin and Pirelli have stated that a 5.5 to 6.0 inch wheel is suitable for either a 180 or a 190 tire width.

That said, I purchased a Dymag with a 6 inch rim so I'm running a 190/50. After previously running a 180/55 on a stock 5.5 inch rim, I'm pleased with the combination.

Most of the SS 600 riders are using 6" rims and use 190/55, gives them more side grip. Had a 6" Mag rear wheel for the DSC track day on my 748R with a 190/55 on it, found no problems.

I have 6" rear Mags on both my 998s and run a 190/50, the 180/55 tyres just don't sit right on them as far as I'm concerned it looks wrong.
My 996 is still on a 5.5" rim with a 180/55 and its hard to tell the difference between the 190 on a 6" rim and the 180 on a 5.5" rim
