Very slight thump but it's friggin cold out. I'll get back to ya Monday.

agree colder than ????????. I don't like the hardness of the tires with high pressure, at lower pressure the tires absorb some of the shock on my back. I will sacrifice tire wear over my back problems. Especially crossing roads at entry gate's running over the gutter ditches.

Radial tires have softer/more flexible widewalls than bias ply and is far softer going over "crashing" bumps. The tread on a radial tire stays flatter even with low tire pressure so you don't get the big bulge in the center tread like you would with bias ply at high pressure or heavy shoulder wear at low pressure.

You can run the Radial as low as 16 PSI and still have decent tread life...A trade-off you will no doubt accept to save your back. I called the villages golf car and they do carry the Roadhawk Steel Belted Radial 205/65-10 for $90 each. I would suggest replacing your 2 back tires at a minimum.

I didn't need new tires but I got 4 Roadhawks tires at $70 each so I couldn't say "No" to that.

On the side of your new tires, does it say "205/65-10" or "205/65-R10"?

The characteristics of these radial ply tires change quite a bit at 75F. I adjusted the first post to reflect the new testing. There is no tire thump at all at. I use a Black & Decker ASI500 tire pump.

Wow 6-8 lbs difference. Did they seem noticeable under inflated at 22-20 and did the increased pressure create a harsh ride?

They did not look under inflated at 20-22 but radial ply tires always look under inflated :)

The increased pressure did not create a harsh ride at 75F. The sidewall flex is still very good. I suspect the ride will be a bit harsher at 60F. I will find out this weekend.

For those with bad backs, I would not run these tires lower than 18 PSI. You should get "decent" wear at that pressure...Better wear than bias ply tires.

For those who want to help save themselves from back pain, the new Yamaha QuieTech gas carts with their excellent independent suspension combined with these 205/65-R10 Roadhawk steel belted radials with a pricey comfy seat should make the cart ride like an old Buick.

So my 2018 Yamaha two seater is set to 25 rear and 23 front. There is so much camber on the front wheels that the tires seem to be riding on the inside more that the outside. I’d did set the front Toe to 1/8 inch toe in and it rides great but I am concerned that the front tires will wear on the inside.

I had one front tire wearing on the inside edge and the other on the outside. I adjusted them flat.

The Road Hawk radial tires run quite differently at 55F and 80F...They also need about 100 miles to break in. With the radial tires, all bumps are less jarring than with bias ply tires. The radial ply and steal belts also make the tire tread flatter on the road and have a larger road tread contact patch regardless of tire pressure.

Sorry, I should have waited for these warmer temperatures and 100 miles of break in before starting this thread but I did not think it would make this much difference in performance.

Mortech,
Would you think the Villages Golf Cart store would be the best place for me to purchase 4 new RoadHawk tires @ $90 a tire? Do you know if that includes installation? Thanks in advance 😊

I got my Road Hawks thru "a friend" for $70 each and installed them myself which is not easy. $90 each at VGC is a good price that I'm pretty sure includes installation - but they might charge you a tire disposal fee on top of that. Worth it just for the smoother ride, IMO.

Not to change the topic, but does anyone ever rotate the tires on their golf cart like we typically do on our cars?

Again, Thank You.
