That's a minor change that shouldn't hurt anything.

 

I know the Kuhmo tires on my 2010 GLS are rated very poor in snow, but the car handles much better than my geo prizm did in snow. It must be the ESC/TCS. I've driven in a few snow storms in Wisconsin and felt much more confident in this car. I did get stuck in my driveway today, but that's because I tried plowing through a ~12" mound. CR rated the Kuhmo Optimo H727 great in the snow for an all season (any thgouhts?) My husband told me I could get these if the Packers won the super bowl, so GO PACK!

 

Just replaced my eight month old Kuhmo's (18,000 miles) with 225 x 17 Continental ExtremeContact DWS. WOW, what a great difference! Car ride considerably smoother and quieter. These tires should be made the OEM tire of choice. The only downside so far has been the loss of about 1.5 mpg, but a worthwhile exchange for the other benefits.

Anyone wishing to purchase four OEM Kumho's with 18,000 miles, they are available for a very reasonable cost. Tires were rotated every 5,000 miles and pressure was checked every weekend. I would be happy to measure the remaining tread if anyone shows interest. Please leave a response and i will contact you.

Vehicle is a 2010 SE.

 

I'm a low-noise freak when considering new tires. Low noise is my highest priority. Traction in the snow is not an issue since I live in the south. Strangely, my Kumhos seemed quiet until I reached about the 5000 mile mark. I see the Continental Extreme Contact DWS has received high marks in this Forum. But I also understand the Michelin MXV4s are highly recommended. And I was satisfied with them with my previous car. Has anyone installed Michelins on their Hyundai?

 

2009 Tourng 30k on tires. Replaced them with Mich pilot sport as plus...225/45zr-17. I like the Mich better than what was on the touring but I really can't say that there is a big difference. Keep in mind we are in the Atlanta area.

 

Also in the ATL area, and since there is no real snow fall, I can't say anything about snow performance of the Kumhos. I feel they are average at worst tires so far with about 17k miles on them (all highway). I suppose that Michelin tires would perform better, because they usually do.

 

I am at 40K miles on the original tires down here in South Florida. that's on a 2010 GLS. Rotated every 5k miles and still have about another 6 months or so left from looking at the wear bar. I usually get about 50K out of new tires and have been using the economy ones on my previous cars.

On this last rotation I do feel a little bit of a shake when doing more than 70mph. They probaly need balancing but I'll just replace them soon. Since I usually ride with kayaks and bikes on the roof. I am used to a noisy shacky ride

 

I got the Continentals ExtremeContact DWS and I have to say they are excellent. My wet traction is miles better than the OEMs, and the ride is a little smoother. noise is about the same. Handling/cornering seems better too.

 

I'm looking to replace my stock Kumhos (32k miles! Not bad) with the Continentals that everyone here loves so much. However, tirerack (and most everyone else) is out of stock of the 215s so I'm looking to purchase the 205s at a similar price since they're not out of stock. I did some envelope calcs and noted that this would mean a 1.5% reduction in tire diameter which leads to inconsistencies in speed reporting, mileage, and potentially MPG calculations. What are peoples' thoughts on this sort of thing? Ignore it? Can you tell the computer to use a different tire size for that sort of thing?

 

Personally, I'd wait for the correct size but a few other sizes would work:
- 205/45 (1.6% shorter)
- 235/40 (1.0% shorter)
- 225/45 (1.3% taller)
- 205/50 (1.9% taller)
