Larger Sidewall tires to soften the ride on 2011 Genesis V8

[gpjlytham]

Hi All

Our 2011Genesis V8, is getting ready for new tires (inner tread is wearing, is that normal?).

The car currently is running on 235 50 r18 tires. Has anyone put larger sidewall tires on their Genesis?

Did the larger sidewalls give the car a smoother ride?

How much did it affect the handling of the car?

What size did you go to?

I know that a larger sidewall will give me a larger tire and therefore it will affect the speedometer reading but what difference have you seen?

The wheels are in good condition so I don’t want to change the wheels, just the tires need to be replaced.

Thanks

Why not just stick to the OEM size to avoid other issues and shop for a tire that is highly rated for comfort etc??

Normally a short sidewall equals better handling and a poorer ride. I have only raced the car once (total blast) but it is my wife's daily driver and comfort is more important than racing. We love the car and any tire suggestions would be a help.

I'd just go to TireRack . com and put in your cars info and read the reviews posted there.

There can be a large difference in ride quality between brands without having to play sidewall games.

The old OEM Dunlops were horrible at just about everything but ride quality (very squishy). Hankook is similar to Dunlop (horrible at everything but ride and quiet).

Bridgestone Turanza Serenity tires have a nice quiet ride on my wife's car (Solara) and good wet grip here in rainy FL.

Lots of folks like the Conti Procontact or Extreme Contact DW for a balance of handling, ride, and grip.

My Michelin Pilot Super Sports have a stiff sidewall, so there's a lot more feedback from the road surface. Handling and wet grip is superior with the MPSS. Pilot Sport 4S is the newer version of this tire. If you're going for sporty, this tire (MPS4S) is for you.

If you want to spend the money, you could go back to 17" rims, and a 60 series tire. This will give you more sidewall. Might lose a little handling. This is what is on base model.

Check the charts on tirerack.com and look for the best riding tires. I was very pleased with the Bridgestone Serenity and purchased three sets over 220,000 miles traveled with my 2011 4.6 Genesis. Michelin has several all season tires that are smooth and quiet

I normally buy name brand tires but Walmart have some tires that are very inexpensive. has anyone tried them? Radar Dimax AS-8 Tires 235/50R18 101V BSW $64.14 per tire. The ratings on walmarts page are very good.

What kind of car and who is the driver doing the rating?
"I thought they were very nice when I drove my 1987 Escort to the doctor's office for my weekly numbness treatment"

I'm skeptical. They may be great around town but not sure I'd want them for a long high speed trip where you can run into bad weather. They do have a V rating though. I don't know that the average person can tell much looking at a tire either.

After reading reviews here, I'd not want them on my car

Please be sure to have a four wheel alignment completed when new tires are installed. Sounds like there may be adjustments needed, due to inner tread wear. Any way you look at it, the Genesis has a bit of rough ride, due to stiff frame. My only dislike with the car, but not bad enough to go with another auto. I went form Michelin tires to Continental Pro Contact. Slightly more noisy, rides rough when tires cold. Otherwise a very good tire. My dealer suggested keeping 35psi on tires. Low profile tires with alloy rims tend to drop pressure in cold weather. 35 psi will not denigrate ride at all.

that website is for the R8 and the tires at walmart are AS-8. and the website is from UK and driving is very different in the UK from Scottsdale AZ. People drive like crazy foo's in UK, lots of great curves and roundabouts. I love driving in the UK, but i now live in sunny Scottsdale.

In the heat of AZ I'd even be more concerned. Your money, your choice.

we bought the Radar dimex tires from walmart, ordered online, delivered to the store and fitted at the walmart tire area.

I am very happy with the tires, they are quiet, appear to handle well (not raced the car but seat of the pants around town) braking appears to be good but again not racing.

We have driven a few 1000 miles and they are good value, lets see how long they last. I think they came with a 60k warranty.

I put Cooper cs5 ultras in oem size on my 2011 4.6. bounced them on the ground and felt them up prior. Nice and thick They’re rated for 150mph+ and 1500 pounds each so yeah they’re going to be stiff... Handles great wet or dry, and I drive FAST. When it’s safe of course...

As for the road noise; it is significantly quieter than my old kumho ecsta tires. Sometimes you can’t even hear the road at all...

But I’m cheating a little bit. Okay, I’m cheating a lot bit. When I am thinking about road noise, i’m not thinking about tires.

I’m an audiophile so of course I have the amps and subs and music that pisses everyone off, but I also have my entire rear seat sound deadened to the floor, the entire trunk lid, the factory sub deck, the tin can of a spare tire bay, and the rear quarter panels.

All you need to know is that the rear half of my car sounds like wood when you knock on it rather than a tinny sheet metal. This significantly reduced the road noise. It ABSORBS vibrations. Bass stays in, road noise stays out. Hyundai did a good job sound deadening the engine, front wheels, doors, and floors, so I left them alone. The rear end though? Not so much.

Hope this helped some of you guys out with your desires to change the sweet oem tire size to something else. Even if you can’t do it yourself, you can have a professional shop do it for around a few hundred... probably.

Just my 2 cents, but last fall I put Continental ContiPro DWS on my 2012 3.8 and I’m pretty pleased with them so far. We had a little snow this winter and I got by without snow tires. I notice a little vibration when cold, but that goes away after a few miles.

In most cases, you get what you pay for, and there is no magic when it comes to manufacturing tires. Materials, labor, the cost of press time. I would almost bet that these Walmart tires were made in China.

I am a notorious cheapskate when it comes to some things, my friend admonishes me for buying “bottom shelf booze”. But when it comes to tires, that is something I won’t skimp on. I think my 4 tires plus alignment came to around $800-$850.

Lest you think I’m a fan of Jacquin’s, (Philly’s Finest), my buddy likes Russian Standard, but I will buy Sobieski and pocket the $15 difference. He likes Maker’s Mark, I go for Buffalo Trace.

I had to resurrect this thread just so I could say this: "Bottom Shelf Booze" sounds like a good name for a rock band. LOL

This is good to know. I've wondered before where the main source of the road noise in these things is located.
