Comparison to Stock OEM Tires
 

How do these tires compare in terms of grip to the Michelin Primacy HP tires?

I bought my car used and these all season tires came with it, so I was wondering if they offer approximately the same amount of grip, less, or more. Can someone be able to tell either according to experience, the tread pattern, or those numerical ratings?

I don't have any first-hand experience with that tire, but based on the description I expect it would be similar with maybe a little bit better dry performance. Generally in the same class, though.

No experience either but they're an all season 460UTQG vs the stock summer with a 240UTQG. Based on this, I actually expect these to have lower grip overall and a lower acceptable temperature range and be longer lasting. Will be fine for regular fall to spring driving but I wouldn't track on them because I imagine grip would fall off quickly as the tire is overheated.

Thanks! I was wondering about them because I accidentally "drifted" turning right at an intersection when I was only going at around 40 kilometres per hour with the traction control and the vehicle stability control both on. Somehow the rear end still came loose with the tires screeching and that really threw me for a loop.

Edit: 40 kilometres per hour = 25 miles per hour

what was your tach reading?

It was around 2000 RPM. Not high at all.

Correction for above, I meant to say spring to fall meaning I wouldn't use them in the winter.

Anyways, sounds like you got oversteer there? 2000RPM at 40km/h would mean you were in third. I couldn't get the rear to step out on the stockers in that situation but with the lower grip of those tires I can imagine the rear would step out if you blitzed the throttle coming out of the corner.

I never consider turning off the traction control when driving on a public road, and now I will probably not even turn off the vehicle stability control with the car being this tail happy.

Oversteer is the nature of a front engine, rear wheel drive sports car. Yes, you should leave all of the nannies on while driving on public roads. They have definitely saved my car on multiple occasions and possibly my life too.

While I think taking a 90 degree corner at 40km/h is a bit too fast, I don't think it should be an issue even on those tires as long as you are doing it right. Just get your braking done before you enter the corner then be gentle on the throttle until the car is pointed straight again.

Haha. Don't worry, I have never turned off those controls yet and won't about to now.

I had similiar situation before, taking a 90 degree corner with everthing on.
Stock tires aren't that safe.

Generally, "summer" and "all season" are misnomers. Summer tires, like the Primacy's, have much better dry and wet grip than All Season tires. The name "All Season" stems from the fact that it is a compromise, giving up good dry/wet weather grip for better cold weather performance. Since the OP is from "The Land of Always Winter", I guess technically, they're better of with the All Seasons :thumbsup:

Oh, I did not know that the OEM Michelin Primacy HP tires were summer tires.

I just thought they were also all season tires.

They are not all season (IIRC that's the reason why in some states, where cars are more often sold with all season ones, they are replaced with other tires, don't recall which ones though). They compromise on some other ground, giving up some grip for lower rolling resistance for more economy and less thread wear for longer life. That lower grip eases fun of getting rear sideways even with low stock NA power level though :) and which probably was the reason of selecting them as stock, normal grip summer tires even of same size will make it a bit harder to do, at least in slower speeds.

Yep, I got that. :)

I know that the Toyota 86's sold at some states in Australia have differing tires, so I guess giving them all season tires rather than their stock summer tires must be the reason. Though that is still weird to me, as 95% of the country does not have to deal with snow.

RandomDeception: no, i'm not speaking about Yokohama Decibel E70 (also summer tyre) of 205/55R16 size for lower trim FR-S in AUDM or other markets also offering 16" stock wheels, but about ones sold in US. At few states with traditionally cold winters IIRC FR-S came prefitted with some all-season tires.

In Aus we only get the Michelins on the 17" wheels and the Yokohamas on the 16" wheels. We don't need all season or winter tyres here. I had never even heard of all season tyre until I started looking at international forums.

Nothing wrong at all with the stock Michelin Primacy HP's...the car is fine taking medium-tight 90 degree turns on them at 40mph in the dry with the traction system off (which is how I always drive, this is the first vehicle I've ever owned that has any kind of stability or traction control). The more I drive on the tires the more its apparent Toyota knew exactly what they were doing...you really don't need any more tire than the stocks for street driving, they do everything very well and are competent in all weather conditions.

At first I was of the opinion they were an 'okay' tire but 'sucked' in the wet...because I was coming from tires that had higher limits and were incredible in the wet. But now after actually spending a lot more time on them and getting to actually know there characteristics and how the car works with them I've come to the conclusion they are an EXCELLENT all around daily driver tire (wet or dry), just a little too expensive. Tires are so good I love them in the wet with the 'nannies' off...great feedback/communication to let you know how the car is managing its traction and lets you balance it near flawlessly.

There is no issue with the stock tires or car in either wet or dry with the systems 'off' - what may be of issue is the driver's ability. Instead of relying on the 'nannies' to 'save you', look into taking some performance driving courses designed to properly teach vehicle control.

Oh, I see. I did not know that the United States regulated that, as none of the American reviews ever mentioned it.


Ah. Now I know. Though, I thought the mountainous regions in New South Wales get quite a bit of snow in the winter season with how well the Australian Winter Olympic snowboarding team performed a few years ago.

RandomDeception: no, imho it's not US regulation of some kind for dealerships, but rather regulation that in some snowy/icy known for cold winters states driver must use winter or at least all season tires (don't know about traffic rules in US, but it's this way in most north-ish enough EU countries), hence dealerships themselves by own choice put instead of original stock primacies all season ones to not have issues with quickly totaled or returned as too undrivable if eg. cars are sold during winter. When i was young and dumb i had driven in RWD car with very worn summer tires on ice. It was .. interesting experience. Be it braking, be it accelerating, be it steering .. car keeps sliding in same direction at same speed. These days i want to still be alive :).

I can't seem to find any articles on which American states regulate the tires on cars sold but I will take your word for it. :)

And no doubt snow tires are a must for winter driving in many parts of the world.
