I am hoping to fit a set of road legal track tyres on my Chimaera. The wheels are 16" 7.5" all round with 225-45 16's on the front and 245-45 16's on the rear. Toyo R888 only go up to 225 for this rim, I could put those all round. I am struggling to find any manufacturer providing a 16" track tyre at 245-45.

Any ideas?

Pirelli P Zero C are 17" & 18" only. Anything for a 16" rim

I run Pirelli P Zero Cs on the original 15" & 16" rims for track days. Have also managed to get AP Racing 4 pot brake set up into the 15" wheel so never found the need to increase the wheel size.

You are thinking of Corsa's.

I have 16's on my car.

Pirelli don't list the P Zero C anymore and according to one supplier site P Zero C is being phased out. The replacement tyre is the P Zero Corsa.

True but there are still plenty of stockists with Zero Cs in stock. Corsas are really made for the Porsche market. They are certainly more expensive than Zero Cs (approx £800 instead of about £500) & you've then the issue of having to find a wheel size that takes a Corsa that will also fit into a Chim.

I've tried several different tyre set ups over the years & the Zero Cs are ahead by a country mile.

As with many limited tread pattern track day tyres, road use is of limited value particularly in the winter months. Best to get a second set of rims for your track day tyres. In any event, the softer compound means that you'll get much less road mileage out of a set.

I've just acquired the wheel and AP upgrade and I took an extra set of spiders. Anthracites for the road and a set of silver for the track. I've put Toyo T1S on the road wheels, as there is little choice at these sizes. Toyo's will do for the road once they're run in but I'd rather have something purpose made for the track. I live about 30 miles from Croft and intend to drive there with the track tyres on. I doubt they'll see much road use.

When you say the wheel upgrade, what do you mean ? Is this a TVR upgrade if so where can I get info ? Any photos of the wheel ? How heavy ? AP brake upgrade makes a massive difference doesnt it. Have you tried them on the track yet ? ............ so many questions.

They are five stud Tamora wheels. No good for your car unless you've had the upgrade. The complete kit, wheels, hubs, discs, callipers, pads bearings, seals, etc. is £1,599 but is not available until further notice. Mine is a special, one off, make it your self (all be it with TVR help) version.

That sounds an incredible price all in. I paid more than that just for 305 mm discs, braided hoses & 4 pot AP Racing set up.

The kit isn't fitted yet. There is an increase in weight but it's all on the axel line so the car should be more stable if anything. I hear good things about these four pot AP brakes. I hope the brake balance is OK because the rears are left as is all be it with new AP compound pads. TVR are still over loaded with 16" five stud spiders but they are having supplier problems with the hubs and tyres. I guess they will sort it out soon and the upgrade kit will be back on the market.

I've had no brake lock up at all since getting used to the set up after the first few laps etc.

Thanks for info though - useful.
