The car: 2004 Dodge Neon SRT-4 Tire size: 225-40/18 Suspension mods: Eibach prokit springs, Hotchkis front and rear swaybar Good god. These tires GRIP! On ramp that goes in a 360 turn with my old azenis (205-50/15) at 55mph have nothing on this (at 55 tires did squeel a little). 50mph is pushing it on this turn, we easily did 65mph +/- one or two mph. No tire squeel, easily could of gone a bit harder. The sidewalls are stiff as hell, no tire roll/push just tons of grip around the turn. In the rain the tires are tons better compared to the old ones, thanks to the grooves, and they dont seem to take any grip away when its dry. We got to compare these tires to another SRT-4 with 215-45/17 Bridgestone Potenza RE040's on it. Avg difference of speed was about 2mph, using the bridgestones...but these are near $200 (a piece) tires we're talkin about here. Overall these tires grip and when you think they wont, they just grip harder. The only bad things i guess is the fact that they are so stiff that its very noticable when going over a bump (but who cares, stiff is good). Great tire. Add your experiences as well!!!
