Michelin Pro 4 Endurance Tires – A big disappointment

This summer I purchased a pair of 25c Michelin Pro 4 endurance tires. I hoped they would be a worthy replacement to my 2005 25c Michelin Pro 2. tires They have been a total disappointment and have been retired early.

Right out of the box, they failed to measure up in width to the Pro 2 tires. The Pro 4s do match the width of other 25c tires, but I had hoped they would be over-sized like the Pro 2s.

The tires rode much harsher than the Pro 2s. The tire felt faster rolling but did not feel any better in turns. I did not put many miles in these tires in the last year, sticking mainly to my mountain bike. Then while just riding along, the rear totally failed on me. Split right along some of the visible bands of the casting.

I could get a warranty replacement, but did not. I did not like the tires and would not want a new one. I got a pair of Bontrager AW2 28c tires to replace them, they are so much better. .

Immortal Michelin Pro Race 2

In 2005, I purchased a pair of Michelin Pro Race II 25 c tires. I have ridden them for 1000’s of miles. They are amazing: rarely flat, corner great, low rolling resistance and super comfortable/soft. Some may question how such a large tire (equal to Conti 28’s) could roll well. Up to a point, larger tires have a lower rolling resistance than a thinner one.

One was destroyed in 2007 by a side wall cut while on the C&O near Shepherstown WV. Up there it has parts that are more single-track than rail-trail and cut it on something.

The other simply will not die. I have ridden it lots of places a road tire should not go, such as the trails along the WO&D and years of commuter service. It simply will not wear out, it even outlasted a wonder set of Open Pro/Ultegra wheels I purchased in 2005.

Maxxis MiMo

I got a Maxxis MiMo CX for my cross bike a few years ago.  About $36 retail and honestly sized at the listed 35.

On the first ride out to and into Rothrock State Forest I was amazed.  The tread seems to grab so well both in braking, turning and putting down power on the gravel roads.  Of course, this was compared to the worn out Bonti Jones tires.  The Jones has a reputation of being grippy when new but loose traction quickly as they wear.  The rolling resistance felt a little higher, but not significantly more.

I have never pinch flatted this tire even when pushed the tire into places it should not be such as rocky single track. For those familiar with central PA, trails like like Detweiler, Little Poe Road, Synagogue Gap.

Maxis Mimo tread

The knobs on the MiMo are all complex, with little ramps, small free standing knobs and knobs cut by X’s.  The center knobs began to show wear quickly.  I feared the tire would be worn out quick but am still riding it now 20+ rides later.  The quick wear evidence made sense since this is marketed as a CX race tire and those tend to sacrifice durability for grip and weight.  The initial wearing did not seem to reduce the grip much and even now when it is more pronounced and effects the full face, the grip remains good.  Not sure how it would compare to a fresh example in back to back rides.
