Reviews of FEDERAL parts For Business
Taiwan
I'm running 255/35R18 Federal 595RS-Pro and like them alot. Pretty affordable and nice level of grip.
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).
They seem to grip decent once warmed up, but they are a bit on the loud side.
Federal tires to add sa mga choices
Federals will be really noisy after a few thousand miles. Almost like your wheel bearings don’t exist anymore. Had rs-rr and 615k+. 615k+ is better. Both are way off pace but great budget tires. 615k+ is actually a pretty good tire for hpde.
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.
