On a £30K sports car, yes they are.
prove it then go price some up.
Why, is your Google broken then? Look, I'm sick and tired of having this same argument with you over and over again, it's getting very tiresome. I'm not actually referring to price at all, budget can also be used as a term of being not very good, and that's exactly what the T1-Rs are: Not very good. They have soft squidgy sidewalls that give a mushy ride, a compound that melts as soon as you get any heat into it and with 300bhp and 1.5tons you will get heat into it, and wet handling that is average at best. If you want to run them on your car then that's fine, but you might as well chuck another 500kg in there, detune the engine and swap the brakes for chocolate as you're basically hamstringing the car.
It's a sports car that enjoys being chucked around, so what's the point putting tyres on that are just going to dull the performance just to save a couple of hundred quid? Since your calculator appears to be broken I'll do the maths for you: It's the equivalent of £3.84 a week to go from the T1-Rs to the VUS. That's absolute peanuts, and if that is still a huge sum of money to you (or anyone else) then you've bought the wrong car. The Zed is a £30K car with £30K car running costs that should have quality parts put on it. If the only other tyres available were PS2s then there might actually be a case for not wanting to spend £1K on tyres for the car, but as there is a bloody fantastic option available in the VUS then there is no need to put rubbish crap on the wheels. None whatsoever.
They may not be utterly pikey brand like a Nankang, but they sure as hell don't belong on a decent sports car. Chuck 'em on a cheapy MX-5 where the weight and power aren't such an issue and they're perfectly acceptable.
I'm really not sure what you're trying to say here, I wouldn't mix different N-spec tyres front and rear. I've got a fair bit of life left in the RE050As I'm running but the rears will need doing long before the fronts, and when that happens I'll probably change all four to the PSS if they're available in N-spec by then. Again, a large cost, but one that I need to do to keep the performance of the car right. I could just chuck a load of crappy Toyos on there but then I'd be left with a car that has less grip, less composure and worse braking capability which might be acceptable on a family shed, but personally I don't think it is on a performance sports car.
Look, this really is going to be the last discussion I have with you on this because all you do is oppose my opinion without giving any reasons why, and not only is it frustrating for me to read it's probably boring to others now too. I'm not a professional, just an enthusiastic amateur and I don't expect to change the world but for every ten people who ignore all the good advice given not just by me, but by others on here with equal and greater experience than myself, there's the odd one who does make the jump and is genuinely grateful that people are prepared to share their knowledge: When you get them PMing you personally to say thanks it makes everything worthwhile and brings a smile to my face. If you want to make your car worse than it was than when it came out of the factory then that's fine, I genuinely couldn't care less any more.
