pooh Posted June 3, 2002 Share Posted June 3, 2002 My live axle is running 13" wheels with 60 profile tyres. Correct me if I'm wrong but probably a good idea on the track(?) On the road the car does not cruise comfortably at high speeds. I'm in the market for new road wheels and rubber. Question is, should I go for 14" wheels on the back with 60 profile? OR 13" with 70's? Is it a good idea to have differing profiles front and back? Can I get 14" alloy wheels -Not from Caterham certainly! Then -probably an age old question- what is the recommended rubber at the moment for the road? Link to comment Share on other sites More sharing options...
Casbar Posted June 3, 2002 Share Posted June 3, 2002 I run 185/70/13 - Yoko's AO21R's - £40 from George Polley's Link to comment Share on other sites More sharing options...
Tonycaterham Posted June 3, 2002 Share Posted June 3, 2002 A lot depends on whether you have a 4 or 5 speed box and the diff ratio. If running 4 speed box could upgrade to 5 speed (Type 9) for less than the cost of a new set of wheels. I run live axle 3.62 diff 5 speed box and 13 inch wheels (021Rs 60 series) 5th gear is for relaxed crusing only. I am changing to a 3.9 diff for sprinting and track days but will then probably have to go for a taller first gear. Tony Link to comment Share on other sites More sharing options...
Violet Elizabeth Posted June 3, 2002 Share Posted June 3, 2002 Running the same as Casbar. No noticeable difference in sump clearance from the 15" + Michelins. World of difference in handling. Link to comment Share on other sites More sharing options...
