Is the Michelin Primacy MXM4 the Best of the Best?

Michelin Primacy MXM4One of our most frequent requests for passenger car tires is for something quiet and comfortable, often regardless of price. Based on our testing and customer feedback, our best recommendation is typically the Michelin Primacy MXM4.


The Primacy MXM4 (which is not to be confused with the similar Primacy MXV4) has quickly become one of our customer's favorite choices for standard and luxury sedans and coupes from Honda, Toyota, Mercedes-Benz and BMW. The newer MXM4 features Michelin's Green X technology for lower rolling resistance while still providing responsive handling in dry, wet and even light snow conditions.



Our extensive evaluations on the Performance Test Track course and Real World Road Ride loop have shown the Primacy MXM4 to be head and shoulders above similar Grand Touring All-Season tires when it comes to comfort, handling and longevity.

I changed from 19" wheels & summer tires to 18" wheels and (winter) Blizzak tires on my BMW 335 Xdrive sedan. What tire pressure should I be maintaining on those tires?

Assuming you are using 225/40R18, 32 PSi would be the minimum. I'd have you use 35 PSi to have a little reserve.

what is the correct tire pressure for BFG all terrain t/a ko LT245/75 R16 120/116 S @80 psi tires on a 2003 ranger xlt ,ext. cab, 4x4, 4 liter eng. with a bed topper. usually lightly loaded on highways?

I'd have you run at least 50 PSi given the Ranger isn't rated for really heavier loads.

I have a 2011 Toyota Tacoma TRD. Door jam states 29 psi cold. I just put a taller tire, Goodyear Trailmark P265/70R 17 on it. Should the same 29 psi be correct?

The taller tire has more load capacity (due to the larger air chamber), so running the same PSi is fine.

Curious what your recommendation is for running LT305/55R20 on a 2013 Silverado 2500 HD. Currently have been keeping them at 60 front and 65 rear.

The LT305/55R20 has a max load capacity of 3,195 lbs at 65 PSi, but your rear axle is rated for 7,050 lbs. If you were to load down the rear axle close to that weight limit, you could blow out the tire. We would not encourage using this size !
