The HTRZ features a highly-engineered offset “V” directional tread pattern that efficiently removes water from the contact patch and prevents aquaplaning. The solid centre rib helps maintain the car’s directional stability even on rain grooved highways..

I was surprised when these tires were installed-the technician balancing the tire/wheel asmbly (stock 8" wide Formula alum wheels) said he NEVER used so little weight on a tire, let alone so little on all 4 on a vehicle... I was then surprised at the great ride- I verified the pressure- 31lbs frt 30 r as ordered. on my 1st "frisky" launch (6spd manual)the engine bogged! The Yokohamas I replaced would freewheel with same start. Car: '02 Pontiac Firebird Formula Engine: 5.7ltre LS1 alum V8 385 rwhp@5600 rpm 425ft/lbtorque@ 5200rpm 3300lbs Trans: Getrag 6spd manual w/5th & 6th overdrive 3.42:1 rear axle w/ limited slip Koni shocks & struts performance change: Yokos: 0-60 mph = 5.0sec 1/4 mile = 13.6s@105mph HTRZ: 0-60 mph = 4.3sec 1/4 mile = 12.9s@107mph 0.7 sec faster 0-60mph! I did not add nitrous oxide just these tires! Then it rained. awesome rain tire- start-stop-turn as if it was dry with the Yokos. Now they are quite worn, but still work great dry & not slippery when wet. I am ashamed to say I have yet to rotate them, but after 26000 miles they have held up well, since I drag race alot and love a twisty road. I can stop so fast with these tires, when i let off the brake as it stops it will propel the car backward from sidewall elasticity unwinding. WEAR-I knew they were soft, but, at the price at Tire-easy.com I could buy 2+ sets of these for the cost of 1 set of high end Goodyears. If you drive like me, and you dont like these tires, no-one can help you. I had one slow leak from a large nail, had it repaired & thats it for problems. even without rotating, the right front tire has a slight bit more wear on the outside edge of the tread than the others-enjoy. By the way, I have a hard time trying to "drift" this car with these tires-too sticky guess I need more power & a tougher clutch. & more rear sway bar.

These are the worst Z-rated tires I have ever had. They were a joke. I ended up selling them on Craigslist to get RID of them at a very big loss. They were the wobbliest, loosest, softest, most dangerous tires. I put them on the back of my GTO and immediately the car wobbled. It was like driving a Ski-Doo from 35 mph on up. The back end kept bouncing and kept swaying. I took them to a specialist who said they were just very cheap tires. I will never order from Tires-Easy again, nor will I ever order that brand again.
