gvwr for boat is 2800lbs and trailer is 1000lbs But still cannot find what the center hole diameter is or how to measure it. looks like all 6 bolt patterns are the same , 4,5,8 bolt patterns can be different. or that is what the video says. just looking for a spare rim and tire.
@Brett D. So the boat and trailer have a combined 3800 pounds GVWR. Great, what bolt pattern did you find? What is the pilot hole size? Are your wheels attached with flat head bolts or tapered lug nuts? Bolts are for "bolt centric" attachment and we will have to know the pilot hole size. If you have tapered lug nuts, then you are "lug centric" and we will know the bolt pattern.
@LesD
@BrettD do you have lug nuts or bolts? How many per wheel?
Looking for a rim and tire for 2013 Four Winns boat trailer 190 gs boat. 6 lug and tire size is 225/75d15 , replaces h78-15st Wants to know center hole opening.?? Not sure what he means
The "center hole opening" is the pilot hole in the middle of the wheel. I have attached an article about that. You should also measure the "bolt pattern" using the other attached article I have linked below. A new tire and wheel must be rated to support your trailer and boat weight. What is your trailer's GVWR?

I want to lower the ground clearance of my camping trailer so it stands more or less horizontal when coupled to my car. The tyres fitted now on the trailer are Goodyear Wrangler AT/SA 215 R15 109/107 T (no aspect ratio given) and result in a fairly steep downward angle of the trailer when coupled to the car. Because of a factory-fitted tow bar that can fold away underneath the rear bumper It is not possible to raise the ball or tow bar. Will fitting 14" wheels and suitable tyres lower the ground clearance by about half an inch and fitting 13 inch tyres lower the ground clearance by about 1 inch? Please help me, thank you, Henner.
I would like to help with this. What is the year make and model of this vehicle? Are you sure there is not an aspect ration marked on the tire? Could this be a European tire size? We are going to need the aspect to figure out which tire would be lower in height.
@LesD Hi Les, thank you so much for replying. The camping trailer I have was made here in South Africa (not Australia) by a small company called Offtrax Off Road Trailers which seems to have gone under as they no longer have a website anymore. The model is called Outplay. The trailer's basic statistics are L x W x H 3900x1725X1250mm, GVM 1800kg, Tare 440kg. GA, V and A all 1800kg. I could not find the aspect ratio on the tyre itself but a tyre dealer here said it was 80. The tyre has the words "Made in South Africa" on it. I hope this helps. Regards, Henner.
You are saying that your current tire is a 215/80-R15, which will be 28.5 inches tall from the ground to the top of the tire. You will need a tire with a smaller aspect number for a lower profile. For instance, a 205/75-R15 like the Kenda Loadstar # AM1ST92 is 27.1 inches tall. Watch your load ratings as smaller tires carry smaller loads.
Suggest a change: the Dimensions on Your diagrams often show “overall diameter” of the wheel but to be correct the “actual diameter” of the bead is used to calculate sidewall height or tire outer diameter. Maybe easier to understand but not accurate? Am I wrong? But a great article otherwise.
You are correct. If you check out the "The Third Number" section at the top of the article you will see that we address the overall and actual wheel diameters. The rest of the diagrams are drawn slightly inaccurate as far as the lines go but it's just to help make things look a little more clean and easier to understand. If you were to measure an actual 205/75-R15 tire the sidewalls would be slightly different since they technically start inside the wheel, but the overall diameter (which is the number we are really getting at) will be the same. Hope this helps!
My tire size reads 235/80R22.5G 134/131M Could u tell me what size motorhome tire covers I should order please. Thank you
Your tires have about a 37" diameter so that's the range you'll want to look at. Here is a link to our selection for you to filter through.

"WOW! I am impressed! I called to place my order and real person answered, spoke perfect English, albeit a slight southern accent, and my order was sent within a day, shipped quickly and I had it a few days later. I saved over a hundred dollars over local and installed it my self. I cant imagine how that they could do any better. THANKS!"
