Ok so I'm thinking of getting a wider set of wheels for track. but not sure which brands will make the tire size that will suit.

I'm thinking of maybe running a 225 up front and a 205 or 215 out back. I really like the Dunlop 03g's but the size I am after is not on their website...(I am currently using a 195 all round with a 7" wheel with plenty of clearance)

Anyone have any advice from previous experience? or know if this setup will fit/work?

Thanks for any help anyone can give, I want more grip!!
