These 235/60R18 were below average overall. For the first 20K miles, they were great, smooth riding and quiet. The next 20K they were not near so quite and smooth; and wore out at 40K miles, much less than the 55K rating. I live in Houston where heavy rain occurs frequently, so I require great wet weather traction tires. I won't replace with MXM4's for sure.

Drove to Lake George, NY from Jupiter, FL-total of 7,100 miles round trip. Hit white squalls near JAX(Similar to winter white outs). Remainder of trip was mostly dry w/occasional heavy rains. Never once hydroplaned or skidded. Smooth, soft, quiet ride...although tire pressure was 6# low. Local WPB dealer forgot to check tire pressure during tire rotation, nor did they check windshield washer fluid. Added proper air pressure for return trip and noted firmer, more responsive handling. Great stopping/slowing when required as drivers occasionally drifted/changed lanes with out looking. I'll remain a loyal customer!

what a treat to not hear my tires on the highway......no noise.....very smooth......outstanding performance.......MXM4 will be my next set.....next set,,,,,,next set.....you get the idea

Based on the first 1500 miles these are great tires and I noticed an immediate reduction in road noise and better handling over the OE tires that came on my GMC Denali Terrain.

I did a ton of research and decided on these particular run flats for my BMW 3 series, I have only had them for a few days but we did have a huge downpour yesterday on my way home from work and I never felt any hydroplaning or instability like I did with my previous set of tires. I am super happy with this set of tires and 10 of 10 would recommend. As for performance we will see but I cant imagine they will not hold up to the brand name.

I agree with a previous reviewer. These tires made a huge difference on my car years ago. But I just put the Primacy on my SUV and I getting lower gas mileage. Where I drive and how I drive hasn't changed. Only the tires. I enjoy the comfort of these tires but the price wasn't worth lower mileage.

I got the tires installed just before winter. Immediately felt the difference in handling. Terrific on the dry road and in heave rain. Total control in heavy rain at decent speeds. I saw no improvement in mileage at speeds over 100k but I noticed some improvement when driving between 90 and 100k. Driving in fresh snow scared the living out of me since the tires had no grip whatsoever. On packed snow they got me to where I was going provided that I drove much slower than I am used to. This is NOT AN ALL SEASON TIRE. Too pricey for just 3 seasons. Bring back the Harmony tire for all seasons.

I've had the tires for 10 days. I used the tires in a variety of conditions & all result in very high ratings. On dry pavement the tires are quiet and I feel very much in control. Handles well at all speeds; smooth, firm, & responsive in a variety of maneuvers. In the rain and these tires do not disappoint in any way. The tires provide good handling & stopping on wet surfaces. I drove with these tires in a 10 inch snow fall in the Chicago area. I am totally impressed with the handling in the snow. These tires are a good investment & I am totally pleased that I made the purchase. Buy these tires, 5 stars!

Great tires, the only brand I have used on my 2 cars, a Jaguar and a Lincoln. They are the best all weather tires. Traction and wear are excellent.

Tires ride smooth and quiet. I don't have a heavy foot on the brake and haven't put a great deal of mileage on them, so everything's great.
