Toyo:
A brief guide to the three tyre types available to the JEC race series.
Whilst all 3 are road-legal and could be used on the street, in reality you'd be off your head to run either the R1R or R888 anywhere other than the track.
The T1R is a more traditional high-performance road tyre. The 888 is as close to a cut-slick as we get, the R1R is an unhappy medium somewhere between the two.
All offer superb performance, and they're each remarkable in their own way, but rule of thumb, for track use, they offer grip in the order they're lined up above.
For a guide to each, and what to fill them with, hit the links below. For the T1R and R1R we've thrown in a little personal experience too. It might save you a few pennies. We can't help you with the 888, too expensive for us, and only run in the "Powered By" series that we don't race with.

The main Toyo site offers some helpful basic info on the tyre construction in general, we stole their text and reproduced it below for your convenience, but check out their site for more:
Every Toyo tyre benefits from our huge investment in the very latest tyre design and technology. That's why they not only have superb grip in the wet or dry, but also feel safe and stable, produce the minimum amount of noise, and have a long life.
They also feature a number of technical highlights that demonstrate Toyo's thorough understanding of how tyres are used and what you, the customer, expects and needs from them. Here are just a few of our innovations.
Rim Protector
Alloy wheels are expensive items, so you don't want to damage them. Many Toyo high performance tyres have a protruding lip, a rim flange protector, at the point where the wheel rim and tyre meet. So if you happen to make a mistake (we're all human, after all), it's the tyre's rubber ridge, rather than your costly alloy wheel, that takes the knock.
Spiral Winding Contruction
Underneath the tread blocks of your average radial tyre are a number of steel belts running around the circumference of the tyre. These belts each have a join line where they splice together to form a hoop, and these join lines can have an adverse effect on ride quality, noise, and high-speed stability.
To overcome this problem, Toyo engineers have developed a unique Spiral Winding technology. This consists of a continuous band of 15mm nylon cord wound around the circumference of the tyre, that covers over the belts join lines.
The result is that our H, Z and W speed-rated tyres will give you a comfortable ride, be easy on your ears, and offer outstanding high speed stability and predictability.
Frankly, we don't know much about all that, we just know that it lets you do this:
