Hello,

I am my car since last March and need to change my tyres. The current ones fitted are Pirelli 245/50 ZR17 99Y, but it looks like they don’t make it anymore with 17 rim only available in 18/19/20. The only brand I found with these dimensions is Accelera. I’ve never heard of that one, not sure it’s good one. If someone could help, that would be much appreciated. 
Thank you!

Yes, 17-inch wheel size tyres are in really short supply these days. Most folks elect to swap to 18-inch rims, which of course means new wheels, but at least there are a lot of suppliers out there selling second-hand XK8 rims. That seems to be the first choice for most folks, but doing a quick look around the internet for Accelera tyres, there is quite a lot of information, with one site giving them a decent review - see link below.

It looks like they originated from Indonesia, but are now owned by a US company based in Miami. Seem to have a primary reputation in motorsport disciplines.

They are cheap, no doubt about that, but these days that does not necessarily mean bad / poor quality and they do have the appropriate UK certification.

Personally, I would elect to go for a set of 18-inch rims as they would offer me a wider ongoing selection of premium tyres, but be careful as the 18-inch option from the period had a wider section rear tyre over the front, i.e. not like the 17-inch, which are the same section all around.

In this case it really is a case of pay your money / make a choice.

Thank you very much N6 JMX for taking time to research about these tires.
