My wife's 2015 E400 one rear tires:
Continental ContiProContact 265 /35 R18 97V XL BSW MB V-rated

Need to have one replaced (with just 1000 miles),
Can it be replaced with:
Continental ExtremeContact DWS
Same size: 265 /35 R18 97Y XL BSW Y-rated
It's $75 cheaper

Or Must I only replace with orig?

Thanks,

is it a front or a rear one? if front I wouldn't do it.. but if its a rear one I still wouldn't do it unless its for a lil amount of time otherwise its better to have same tores on one axle.... so the answer is... it has to be the same tread which means it has to be the same tire... hopefully this helps , correct me if im wrong

Never use different tires in the same axle.

+1 on same tire. should be fine since other one only has 1000 miles on it. Pothole?

NickTH

Yep.
Damn pothole.
Now wondering if I should've bought the tire & wheel protection policy.
Hope the shocks didn't get messed up...

I think shock/stut would be covered under warranty. Any sign of damage to the rim? That's where wheel protection really pays off if you have low profile tires. Otherwise, road hazard helps for tire blowouts if they offer it and is much cheaper.

You can put on whatever tire you want as long as the speed rating is the same or higher than the factory tire. The tires do not have to match. However, I prefer to at least have the same tires on the same axle, and on a brand new car, I'd want all 4 tires to match. Matching tires on the same axle make the car track better. But there is no rule, except for not going with a lesser speed rating.

+1 same type on same axle. Today's suspensions are tuned to OEM tires but you can vary within informed variances. Look at local dealer for potential "goodwill" replacements also.

Just bit the bullet.
Went to local Discount Tire (only one out 5 closest stores had 2 tires in stock, others must special order on Tues), cost $274, $323 out the door after taxes & mounting fee. 20 minutes later, back on the road with orig new tires.

Flatter wallet, but extremely happy with service with Discount Tires.

btw, I checked with local Costco, Sam's club, NTB, none carries it or has in local stock. TireRack has same tire, almost same price, but $16 shipping fee & wait til late next week.

I just drove a friends 2008 W211 E550 pretty hard with three additional passengers on board. The car was equipped with 245/40 R18 Continental Sport Contact 3 front / 265/35 R18 Goodyear Eagle F1 Assymetric II rear.


While cornering at the limit, the car felt somehow undefined. I could not really say what felt wrong but it behaved weird. After blasting down a straight with approximately 150mph, I had to do an full braking. Immediately the car became unstable.


What was the problem? Well, the front tires did not build up as much traction as the rear ones. So the ABS had to release the front brakes, while the rear brakes remained engaged. Therefore the car felt very unstable. After replacing the front tires with Goodyears as well, the problem was solved.


I would never ever mix up tires again after this observation. Of course: Your wife will not deliberately drive as I did. However, nobody knows, if she will have to brake really hard in the unlikely event of an emergency or do a very fast lane shift...

Safety first. Same tires all around. And: The rear axle is responsible for the longitudinal stability of the car.
