Just bought the car this week. Was told that the 12 inch tires would make it ride smoother than the 10's. It does not seem to be the case. It is hard to explain the ride, seems to jump up and down. I just put the tires to 17.5 lbs and that might have helped a bit. I am calling the dealer tomorror to see what they have to say. Has anyone had any problems or know of a fix .

I have a Yamaha with same problem. Tires probably out of round. I had dealer check them and they said it was ok, but I have done mechanical work all my life and I know better. I have tried different pressures, but doesn't really help. I am hoping as the suspension breaks in it will be less noticeable. I am also going to rotate the tires around and see if that helps any, but if the tires are out of round you can only do so much. The tires are usually trailer tires and are not auto quality. Let us know how it turns out.

I reject one out of every four new car tires regardless of the manufacturer for excessive road force.

I bet the cart tires are the same problem. I have heard stories about being square flintsone wheels.

Have to get a Dial indicator and measure the tire and rim latral and radial runout.

I know on a Tomberlin the stock size tires I tried rode better and handled better than the over size tires.

I test drove many brands and tire types and found the Loadstar 10 inch hi profiles to give the best ride. the sidewall says up to 30 some pounds but 20 seems to be a good number.
I drove a Yamaha the other day 2012 with the loadstars and found it the best riding.

I agree with you about the Loadstar 10 high profile (205/65-10) providing the best ride. My '08 Ezgo came equipped with low profile Loadstars (205/50-10) and the ride I was experiencing was similar to the ride Harleyman describes, sort of bounsey. I replaced them with 205/65-10 Loadstars.

The higher profile tires rides much smoother and also gave me a 2.6 mph increase in speed.

Update. When they took the car back to see what the problem was, the service guy told me that it had four bent rims. I cannot imagine how that could possible happen although they are mag wheels and maybe when they put the tires on the guy might not have known what he was doing and bent them during the installation. The bottom line is that the problem is all but fixed. Because it does not have 8 inch tires, which I think would give the best ride, I am happy with the outcome even though it does not ride as good as the 2004 Yamaha I sold to buy this one.

[Harleyman]

Problem still not fixed. The mechanic told me that the tires come strapped down tight to the trailer and that is why we are having the problem. He thinks that they will be ok in time. I have tried different tires and the problem is still there. Not sure what to do. I am back in Canada until end of Jan so nothing can be done while I am gone. I don't know if I put a lot of air in them and ran it for a week or so woulde help. Any ideas ? It is very disappointing.

If you had four bent rims, that cart was dropped somewhere from the factory to the dealer and dropped hard. If you have replaced the rims and checked the tires for being out of round, then someplace you have additional suspension issues.

[Harleyman]

I asked the mechanic when he came to the house. It was not the rims that were bent, it was the tires that they replaced. I couldnt believe the rims had been bent, would have had to have been dropped from a plane. I just hope that in time the tires will be ok, but I really have my doubts. Very disappointed.

When I ordered my 2012 EZ-GO the salesman told me the same story about rims I had gotten from another retailer as well. Those rims are made in the US and ALL manufactures have had a heck of a time finding ones that are truly round.

I upgraded to the 215/50/12's and it rides like a dream. No exhaust issues with side or back either as it's electric, 6/8's.

About the tires and ride quality. my experience, from many years of automotive work, is that with larger rim diameters and lower profile tires,
you will have a harsher ride. this is just because the sidewall has less height to flex when hitting bumps in the road. imho...

[CarGuys]

JimBev is correct,

It's called stacked tolerance. Get a rim with to much radial and or lateral runout in combination with a Tire with to much radial and or laterial runout , then combine that with a STIFF new spring suspension and you got a bounce mobile

I have heard the loadstar tires are true and better than most.

We are back in Canada for another week and the car has been at the dealer since we left in Dec for them to have another go at it. They tell me that the ride will get better when the tires break in and the suspension loosens up a bit. If these are car tires, like they told me they were, why can't they be balanced. It seems to me that the problem would be fixed if they did that.

When I got my Polaris, the ride was just as described above. I jacked up the front of the cart and spun the wheels, placing a vertical rod in front of each to test the roundness of each tire. Both were significantly out of round (IMO). Before I complained to the dealer about it, I got a call from the manufacturer asking how I liked my cart. I described the problem I had with the wheel/tire combination and was told to have them aligned and balanced. When I told the dealer this, they indicated they did not or could not balance cart tires. The only thing they could offer was to replace the tire. I got to speak to the tech who mounts all the tires for the company and he candidly admitted that most of the tires were out of round. He offered to shave the tire(s) that were out of round but cautioned me it would reduce the life of the tire because it takes tread off. He suggested I simply replace the tire, which I did.

It's now about two years later and the cart still has a little bounce/wobble in it, but either I am used to it or it's a little better than before as I hardly notice it. I did try changing the pressure up and down and found a pressure that works better. For me it is 24. Again, loadstar 205-65/10.
