Roadhawk 205/65-10 tires
 

Just put 4 Rhox Roadhawk 205/65-R10 steel belted radials on my cart. It does ride a bit smoother and cornering a bit more agile. Hopefully they wear better.

I did some testing for tread wear using tire chalk. On a 1000 lbs cart, perfect even wear was at 28 PSI back and 26 PSI front.

The radials are less jarring especially on turf.

Thanks for the info. Good to know. I am getting a new Yamaha cart standard two seater with radials and this info will give me a good starting point for setting the tire pressure.

Interesting re: 20/22 lbs
 

I would expect most villagers do not know when the last time was they checked their tire pressure-or where it should be.

As to change in ride and handeling. I wonder how you compare or what you compare it to.

I would expect the weight of a gas golf cart is more in the rear due to the engine. But, put a couple of .........pounders in the front and the weight distribution will of course change.

As to tire wear-we use our golf cart quite a bit. Our cart is now four years old with original 10 inch bias ply tires on it and they are at most half worn. If, yours is wearing faster perhaps, you should have the alignment checked and/or worn parts.

FOR ALL- your tire pressure goes down dramatically as the weather gets warmer or now colder. Probably a good time to check it in the,"winter." I use a quality hand bicycle pump-a floor pump-new they are like $20.00.

Last I checked both gas and electric weigh about the same. 535 pounds.

Electric cart is more than a gas. Electric has 390 pounds of batteries alone.

The debate on tire pressures will never end, kinda like Gas verse electric carts, but lets not go there.

I keep 32 lbs. in my tires. After over 11,000 miles the wear is great.

Cart + Stuff + Rider = 1000 lbs.

Do the radials run smooth without the thump thump that is common with the bias ply tires?

Cool weather tire looses pressure, warmer weather not as fast. As tires heat up pressure rises. Not to important on golf cars cause the speed and weight don't heat up tires like vehicle going 70 plus on hot day. Regardless tire pressure should be checked once month, good time to check oil in gas cart, otherwise the Big Bang could bring cart to screeching halt?

I got 8k plus miles on my cart, the front tire are verily worn, the back tire are 1/2 gone. Th back tire take most of the weight and momentum starts, stops, acceleration, and corners. IMO they wear much faster.

I would think the tires would be worn in the middle unless you have Curtis cab and extra seat hanging off the back?

That's pretty close to my pressure with no Curtis cab or seat accessories hanging off the back, my back tires wear 3 times faster than the front. I use to rotate them but, didn't like the way they steered.

They are wearing fine, or ok. The 1st 3000 miles, or so, I ran 23 lbs. like recommended by the cart store. They started to wear on the outside/inside. Since running 32 lbs. wear has been perfect, or great, or good, or....

Darn it is cold!

Your running the right pressure

At last I am doing something right!

Sure...IF your cart weighs 3000 lbs.

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.

Yes, you should consider rotating your tires. The rears will wear faster than the fronts. I prefer the rotation pattern where the fronts go straight back and the rears cross over to the front. With rotation, it looks like my 205/65-10 Loadstar tires (a popular tire in The Villages) will go about 30K miles.

I don’t think the camber can be adjusted on Yamaha carts to adjust the tires so they ride flat. I’ll just have to keep adjusting the tire pressure in the front tires until I get optimum tire contact. There is also some negative camber in the rears but the radials are able to compensate for it.
