Default Need a solution having a Problem with upsized tires...

So i did a bunch of research on the forums and read reviews on the best tire sizes to change for better handling and all. I went with the Continental DWS All Season tires sizes-245/35/19 front and 275/30/19 rear. I just got it installed balanced and aligned yesterday and i took it out on the highway today and the car feels a lot smoother than my previous nitto tires but the handling is awful! When i try to make wide turns or sharp turns the car loses balanced and doesnt feel grounded for-- Example-- When i make a sharp turn into the left lane and turn the wheel straight the rear of the car slides left causing the front end to skid right...I really dont know what to do i just spent $1000 on tires and hope theres another solution than buying new tires again and going back to my previous setup 235/35/19 and 275/30/19..

This is the same exact set up im trying to do. Thanks for sharing. Unless you can get a lil bit of your money back, i think you're styck with dws. Or spend another grand for a new tire. Try selling it on classified side.
The only reason i would use continental dws is because i will be going to hawaii for a few years. Hawaii gets some major rain and dws is all season which im hoping it can help during the rainy season. idk if mich pss or potenza can handle that much rain.

Try increasing the air pressure to stiffen the tire sidewalls. Hopefully that helps.

Most likely because you have all seasons on unless you had all seasons on previously. I haven't heard good things about Continental tires unfortunately :-/ Hope you find a solution

I have been running these for almost 10,000 miles in the actual manufacturers recommended size and have had zero issues. I would take your car somewhere else to check on the alignment.

The tire shop could have also mounted the tires inner side out? I'm just throwing possibilities out there.

You don't need All Season tires to handle rain. Max Performance tires (Michelin Pilot SS, Bridgestone Potenza S-04, etc) will do just fine in the rain. However, Extreme Performance tires (Bridgestone RE11, etc) wont. Max Performance Tires however, wont handle cold, ice or light snow.

Drive normal for couple hundred miles to wear off the rubber protection oil. They can't be that bad for street driving, even with the all-season.

Your tires have yet to break in. Be light on your foot for the next 500 miles.

sorry to break it to you but dude you're shoving soft/cheap all-seasons on a rwd car with 416hp supplied by a 5.0 F1 team engine. it's like showing up to your wedding wearing a one piece bikini as the groom.

not a good look - get pilot super sports and be done with it. if you need a winter car, go buy a beater.

Ehh all of you speak rubbish. I've put about 15K on my Conti DWS... all-seasons will not handle nearly as well as performance tires. It's like jack of all trades master of none. I felt the body roll once I switched from the crappy OEM RE050A's (got a unrepairable flat) to Conti DWS. The tires are not cheaply made. I tend to have bad luck with tires but these have held up well. Just drove 14 hours this weekend with no issues (to Canada and back, 7 hrs each way). The DWS are good in rain, as I hit a torrential downpour on the way and I felt safe. There is also barely any road noise. Mike it will take you some time to get used to all seasons, 36psi is optimal. I actually had 34-35 psi in my tires before I left for Canada.

It's definitely convenient not having to store and switch tires season to season.

lol @ Teo's post...

I had DWS tires on the Audi I had awhile back. They have a super soft sidewall so maybe you are experiencing that flex when you are turning. Its definitely noticeable with that tire.
