Re: Bridgestone EP422 tires swapped for Michelin Primacy MXV

Thu Jan 02, 2014 8:50 pm

Anyone can comment about pros and cons of 89H vs. 91H versions of this tire? The 89H is 1.3 pounds lighter which is an obvious advantage, the EP422s are also load index 89 so they should work fine I assume. Is anyone with noticeable decrease in range with MXV4s running the 89s?

had two of them and can't say I saw a difference in range but with slow range degradation, the differences may have simply been unnoticed. but have to say with the delicate sidewalls, the higher load rating is probably a good idea.

Do MXV4s have delicate sidewalls as well? I thought theEP422s' weak sidewalls was one of the main reasons to upgrade to the Michelins.

tire sides are strong and the ride is firm and sticking.

when u have no spare -- even if you are usually within an hour of home -- who wants to play around with a tire that picks up nails easily and busts out with bubbles cause of pot holes and if you hit a curb hard?

have to say better traction is the only reason to upgrade. lets face it; if you don't hit anything and inflate to 40ish PSI, the ecopia side walls are plenty strong enough...

After all I ended up with a set of new Ecrapias today, at least I know what to expect from them. Also I may be selling the car in the near future so I see no reason to throw extra $$ on the Michelins.

i'm looking at tires from costco - i see two michelin tires that are "MXV4" :

Michelin - Primacy™ MXV4
Michelin - Energy™ MXV4® S8

i would assume that the "energy" tire is more of an LRR tire, i guess i need to check michelin's web site.

i had good luck with the MXV4s on my two gen 2 priuses, but with our battery approaching -15% of capacity, i'm a little concerned by dropping the range another 8%. on the other hand the ecopias are pretty bad tires.

anyone know the real-world differences between those two tires above?

Definitely not 8 percent I hope. It really a tough one to accurately evaulate

hopefully. seems like the "energy" tires are just lower quality versions of the primacies, so i guess i'm going to go for the primacy. i can't find anything on michelin's site (well their mobile site anyway) that talks about rolling resistance.

I agree based on my MXV4 experience and second the rationale.
