The growing number of broad market passenger cars equipped with high performance tires raises the question: Is there a high performance tire market anymore? Modern Tire Dealer went to tire manufacturers, marketers and distributors to find out. First we asked for their definition of a high performance tire.
Email Driving on ultra-high-performance tires on a snow-covered road is like trying to negotiate Copper Mountain's expert-level "Drain Pipe" ski run on water skis.
Both are skis, so what's the problem? Even on tires billed as "ultra-high-performance all-season" driving in the snow is like negotiating that black-diamond run on cross-country skis: It's possible, but it's not the best choice. Also known as "max performance summer" tires or, more accurately, "three-season" tires, they come standard on every Porsche except the Cayenneall Corvettes, the Viper, all Ferraris and more.
Summer tires offer more grip on both wet and dry roads than all-season tires, much less winter aka "snow" tires. Tire performance differences Winter tires, all-season-tires and summer tires differ in the pliability and durability of their rubber at different temperatures.
Tire engineers call it "glass transition temperature": Get them cold enough and every tire will have the grip of a Formica kitchen counter. For a race tire, it might be 40 Fahrenheit. For a winter tire it could be 60 degrees below zero. Summer tire tread starts becoming Formica-like somewhere just below freezing.
Most all-season tires are still pliable below zero, but some "ultra-high-performance all-season" tires start losing grip well before that.

At one point in time, "High Performance" tires would have been H rated tires - with a smattering of V rated tires - but the market has moved away from this kind of subdivision in 2 forms. 1) H rated tires are now more designed for regular street usage. The term "touring" as it applies to tires is a marketing term and generally applies to tires that perform better on dry road surfaces than stock replacements, but are not burdened with the comfort and longevity compromises inherent in performance tires.
Grip and sipes Tire grip in the cold is much like oil viscosity, largely because tires contain many petroleum-based products. A weight racing oil will protect an engine at temperatures approaching degrees, but at 70 degrees it's almost as thick as gelatin. Today, most racing oils are "multigrade": A 20W racing oil remains liquid enough to adequately lubricate the engine while it warms up but still protects at prodigious temperatures.
Tires haven't advanced that far. There are many other things that give tires grip in the snow. But you can't put enough sipes in a summer tire to give it useful mobility in the snow.
I have personally experienced summer tires in the snow many times. Once, I got stuck on a perfectly level-packed snowfield. Another time, an ultra-high-performance summer tire would not go forward if the snowy road had any incline, but in reverse it could maintain about 5 mph.
A third was the safest snow tire in the world: It couldn't get out of the garage. Most recently, I drove for a video that was designed to sing the praises of a new ultra-high-performance all-season tire.
We were using a snow-covered track. Air temperature hovered in the low 20s. The client supplied a BMW 3 Series, but that wasn't flashy enough for the ad agency. The ad guys' next bright idea was to have me borrow some all-season tires from Dodge, which was testing at the same facility.
I drove the Charger over to their garage and almost crashed about 25 times in the quarter mile trip. I never exceeded 15 mph: I didn't want to go that fast, but with the brake pedal buried to the floor it picked up speed on a slight downgrade. Dodge graciously offered to loan us some inch high-performance all-season tires.
But over the two-way radio came their test driver's fourth request that day to be pulled out of a snowbank. His car was fitted with the tires we would be borrowing.
I said, "No thanks.NT G2. Does your high-powered Mustang ever feel loose or unstable during rapid acceleration or when taking a corner at speed? If so, it may not be your suspension, like you think, it could be your tires.

This is very different than a touring tire that prioritizes long tread wear and a comfortable, quiet ride. For high-speed precision handling and traction, you need high performance motorcycle tires designed to grip with road with minimal resistance.
Arguably, tires play one of the largest roles in the performance of your bike. Ensuring you have safe, effective and properly fitting tires is essential for.
