OK I'm in the market for new tires as well. I have been running Toyo T1R for 1.5 years and will not buy them again due to wear and product coming apart in half-life. When I first ran them great tires for handling and ride with very low sound in car. The E55 eats these tires up in the rear (like it does most soft tires) but what happened this month makes me think about going with another brand. First my RR tire wore very odd on one side maybe it was the rear alignment off until I found the same thing on my front FR tire which looks like a belt inside the tire came apart at high speed. The rears have been changed once, and I was able to keep the fronts due to tread life on them. The front tires still have maybe 5,000 to 7,000 miles left except for the problem tire, which just happened.
I was thinking of Nitto NT555 but in Miami you need good rain tires in the summer so they are out, but now I may try the INVO I have talked to a few Viper guys that are running them and they love them. But I think the same company owns Toyo and Nitto? I think Toyo has a problem with high heat like Pirelli did back in the 90’s. I see a lot of high-end tuners putting Nitto’s on their cars so maybe these are better then the Toyo brand or Nitto is giving great deals to these shops (Renntech, Steeda, etc)? I have not liked the Goodyear F1 tires, but the Corvette guys seem to dig them. I have not used them on my Mercedes. I did run the Falkens on my S class but the car was to heavy and they burned up fast.
So which tire? The Nitto INVO looks to be a good choice for me due to being low sound, great in wet and dry, but are rated at 260 very soft tire. These may not last on our E55’s. Does anyone have these tires on their E55? What about the Vredestein Ultrac Sessanta I only seen the ads for these and I not met anyone using them yet. Feedback anyone? Thanks
