Set of 4 Kenda Vezda UHP A/S (KR400) 255/40ZR18 99W XL Tires Fits: 2011-14 Mercedes-Benz SL550 Base, 2005 Mercedes-Benz SL500 Base

I've used Kenda tires for my dirt bikes for years and have always been please so I decided to give them a try on my BMW 540i which is a high performance rear wheel drive vehicle. I was a little worried about how I would like these tires since I have had very expensive, high-end, high-performance tires on the car till now, but I have to say, I'm MORE than pleased at the quality of this tire for the price. Will definitely buy Kenda tires again.

I have compared these 19" low cost UHP all season tires with the 18" Westlake UHP all season SA07 tires on a traded vehicle I have had in the past and these KENDA VEZDA UHP A/S KR400 have a AA in traction and A in temperature from a company that also makes bicycle and motorcycle tires. These are true ALL SEASON ULTRA HIGH PERFORMANCE non run flat radial tires even compared to the big brands and more costly (Michelin, Pirelli, BF Goodrich and Continental) will tie or outperform them. Fairly quiet tires at low speeds and moderate performance noise at higher speeds and for the low cost price, these tires are best for German, Japanese, Italian, and American high performance or practical driving vehicles. I certify with stamp of approval for these KENDA UHP tires with a promise guarantee.
