I have a Fury that I use for sprints/hillclimbs and it current runs 7.5/21.5-15 front, 8.0/21.5-15 rear slicks, 7J rims front and rear.

My competition cars have always run narrower tyres at the front, as do most cars I see at events, but production road cars generally have the same size both ends, my thoughts on buying new tyres are to use 8.0/21.5-15 all round.

Does anyone know of a reason not to do this ?

Thanks.

I did think of that but other similar weight cars are running 8" and even wider at the front and not having a problem, the slicks are hillclimb compound so very soft.

A common problem with these tyres/events is graining on the fronts, lunchtime is generally spend shaving this off the fronts, the rears seem to hold up much better. One of my thoughts on running the same both ends was to swap the tyres round between practice and timed runs.

Thanks for the replies guys.

I think I will stick with 7.5 fronts as the car currently handles well with excellent turn in, I wouldn't want to end up with understeer.
