I feel much safer now. These tyres are worth the money and perform well especially in bad weather conditions.

Continental Sport Contact 5

I've looked at different forums for the XK8 and these tyres are suggested for their good grip and quietness, as well as their excellent wet weather braking. I could immediately tell how much quieter the tyres were as soon as I left the fitters, and I've also noticed that the car feels more stable on my favourite B-road. So far, I'm really happy with them.

I see some concerns regarding tyre noise in reviews, but I find it less noticeable, making car noises more noticeable. I haven't driven aggressively and am pleased with them up to now. I'm hoping they last as long as my previous ones, which went for 25,000 miles. That would be fantastic.

255/45 R18 Tyre Dimensions

255/45 R18 is a tyre size associated with executive cars and used on the Audi A8 and the Mercedes-Benz S-Class. The first number is the width of the tyre in mm so here the width is 255mm. The middle number is the sidewall height as a percentage of the width. Here, an aspect ratio of 45 means the sidewall height is 45% of 255mm, which is 115mm. The R means radial and 18 indicates the rim diameter in inches. Therefore, the sidewall height of 115mm in conjunction with the 18-inch rim results in a tyre diameter of 687mm. The A8 and S-Class can both benefit from greater sidewall height as it creates more absorption for bumps on the road. 255/45 R18 tyres are available on Tyres.co.uk.
