Tires FEDERAL or Triangle

Triangles used to be fucking terrible desth traps but ive got a set on a car that i drive very hard at times and they seem to hold up mint these days even in the wet

Ran the original tires for 6yrs just replaced them with some Federal Evoluzion ST-1 225/50ZR/17 high performance tires summer only all Im going to say is money well spent ????

Just the loudest tires on planet earth. Boy do they grip through!

I just went from Federal 595 RS-RR (very loud but performed well on street and autocross) to their 595 RS-Pro (waaaaay quiter, I love these tires so far).

I also own a set of these, I can confirm. Fits my BMW very well as they used to make airplane engines, and these sound like a Messerschmidt prop plane.

The next set of Federal 595 RS-Pro lasted 30k and looked like OP tires.

Chinese snow tires are hit or miss. I had a set of federals for a short while that handled snow great for what they were.

We ran them on our champ car endurance race car. They were ok for what they are. Beware they will get greasy after around 10-15 laps at full pace and grip goes immediately. Caused significant understeer at the limit when this happened.

In size 225/40 (r18), their thread width is comparable to other makers ~205. Well, does it matter? Yes, in the sense that when you install them onto an 8.5 wide rim, you'll notice that you're stretching the fit, and the sweating starts. Installing a tire alone with a basic tire machine is no longer possible.

I got federals once because bills were coming all at once. Worst tires i ever had, so noisy, rough on the road and just didn’t feel great. Snow they were actually great surprisingly.
