Replaced a set of aging Toyo T1Rs yesterday for RS3s on standard 15/16" wheels. Also dropped the widths back to standard 225 to 205 fromt and 245 to 225 rear.

Initial thoughts are that they seem better in town, grip is better and steering is improved with the narrower fronts.

However at higher speeds the car seems to be a real handful, and tramlines an awful lot, especially under braking. A few people have mentioned that they take while to break in, so hopefully this will improve.

Just wanted to check what pressures others are running with the RS3s, 22 front and 24 rear seems far to low to me due to the softish ture wall so spill probably increase this to 24/26

What did you have your toyos on? I've found 25 all round to be manageable and very progressive. (Edit: road)

I've had RS3 put on the rear only, I too found them to be very lively. Felt like when going round corners I had a serious case of passive rear steering, ie ft like no grip, no grip, GRIP. Seem to make the car really unsettled, but they do now seem to be settling down after about 100 miles use and I'm starting to enjoy it again.
I have 26psi in the rears.

Valuable lesson learnt. Don't trust tyre fitters to inflate tries to the correct pressure.

Checked this morning and rear pressures were 24 and 34!! Fronts were 22 and 20.

Now sorted at 26 rear and 24 front.

Been there! Asked for 24/26 or similar, got well over 30 all round. Jittery doesn't begin to describe it. It's amazing how much difference tyre pressures make to these cars.

Never, ever, trust tyre fitters with pressures > always check (and adjust !)

Normally I wouldn't have trusted them. But the fitter did ask me what pressures I wanted and I checked the the first 2 that he inflated. I think the other fitter did the last one though.

Anyway, had a good run today and handling is much better, and a noticeable improvement on the old Toyos. Steerimg also seems better with the narrower fronts.

Where they really come into their own is if you get caught in a cataclysmic downpour and rivers start running across the road. I have them on my Saab and it is on rails, even going through rivers. The tread pattern and soft rubber combine to give you astounding grip.

Never noticed any tram lining, so it was probably the newness plus pressures. On the wear/life front, my fronts lasted 21,000 miles, front wheel drive car, and tears are still going at 30,000 miles. So they should outlive the car if you are a typical TVR owner.....

I changed to RS3's before my Europe trip a month ago and even with correct tyre pressures (22/24 on 17/18's) I've never experienced as much tramlining for the first few hundred miles - had to check camber and geometry it was that bad.....
but all good now settled in and have done over 4000 miles on them in the last month and they are great for normal/wet use (had monsoons in France).

Only negative comment is after a ouple of hours of twisties in Europe you can get too much heat in them and they 'go off' although very predictable in their nature....
