I知 planning on purchasing for 13 6MT the Michelin AS3+ soon but was wondering which speed rating would be better.

The oem mxm4 is 96v and I知 thinking of choosing that for the AS3+ when I replace the oems.

Any suggestions?

Thanks.

Unless you're going to be tracking the car, pretty much any tire in the size which will fit will have more than high enough of a speed rating for anything you're doing to be doing here in North America.

I would just go with V rated like the OEMs. I do think that the lower speed rated tires are a little softer. So it's up to your driving. I'd still stick with OEM specs though.

Auto's are limited to 125MPH, not sure about the 6MT. Anything 125+ will be absolutely fine.

I'm like 90% sure I read somewhere the 6MTs for both the 3rd and 4th Gen TL are limited to something like 155. I'll see if I can dig up that reference.

Not sure if you have already purchased your tires. I have AS3 100Y XL that were purchased on Tirerack. I love the stickiness on it, but it does right considerably harder than the Mxm4 9V.

Today I just purchased the A/S 3+ 245/45/18 96v to replace the oem mxm4.

For some reason my speedometer is reading faster than what I知 actually driving by 10-15 mph.

What could be the issue, considering the size is the same as the oem?

No air pressure in the tires at all? Driving across an ice covered lake with your foot mashed all the way to the floor?

That kind of delta between indicated and actual is huge and cannot typically be caused by tires. Said another way, you would have needed to put something like 245/20 R18 tires on your car, assuming they existed, to cause that level of a speedometer error.
