My other 1303 GL

[Steve C]

I've been running 245/40 x 18 Mickey Thompson ET streets, these were 2nd hand and pretty old and the side walls don't have a lot of give.

A local speed shop had a special on some M&H 245/55 x 15 drag radials.

There was no 15 inch Porsche factory wheel that would work because my wheel bolt face is pushed out a long way by my 944 trailing arms so I had a pair of 15x6 Cookie cutters widened on the inside to 8.25 inch to take these tyres. They worked out at ET 65.

My local tyre guy did a finger balance rather than a cone balance for me
