I think we have to take it one step at a time.
225/50YR15 P7 is available https://www.longstonetyres.co....relli-cinturato.html that is a step forward.
345/35ZR15 P7 will be available any day now https://www.longstonetyres.co....li-cinturato-p7.html also good news.
285/40ZR15 P7 available soon. that has to be a massive step forward for you guys, because that is an odd tyre sized, that is doesn't really make sense to make. However Pirelli are currently celebrating there heritage. so we benefit. and by benefit. It is my business, but i will trade fairly. so look what you can currently buy a 345/35R15 tyre for and if all goes well you will be really pleased with the price of the up and coming P7. Also bare in mind that the 255/60R15 CN12 was only available through Lamborghini the were over 1`500 GB P https://www.longstonetyres.co....-cinturato-cn12.html
Here is where i'm going to get controversial. fitting 345/35R15 tyres on a car do not make it handle well. it gives you epic levels of grip, but it doesn't make it handle. and fitting 285 section tyres is just bonkers. However, i do get it because it is cool. but lets not kid our selves that massively fat tyres make a car handle well, cos they don't. yes straight line stopping is epic. yes for the staggering amounts of power it does diminish wheel spin, but it does not handle. you can't change the laws of physics.
The question of 285/50R15 P7 tyres. for now i suggest fitting 255/60R15 CN12 Cinturato. If you want wider then 275/55R15 Avon CR6ZZ https://www.longstonetyres.co....vr15-avon-cr6zz.html or 295/50R15 CR6ZZ https://www.longstonetyres.co....vr15-avon-cr6zz.html please don't fit wobbly side walled crap tyres. have some European carcasses on your tyres.
I can't believe you would consider fitting an S rated tyre. what make of 295/50R15 are you fitting.
It may have sounded like i was criticizing Pantera Doug's choice of Avon CR6ZZ tyres, but really until recently they are by far the the best handling tyres. I mean by miles. what 295/50R15 are being fitted currently?
Please don't criticize Pirelli for what they are doing currently because it is brilliant!
As to making 285/50R15 P7. may be it will happen. specially if the 285/40R15 P7 sells well
