Wheeler pulling hard to the right on pavement?

[fabiodriven]

Very feasible for two tires to have two different contact patches and track straight with two different pressures. I've seen it many, many times. My current SX rider I've been riding for over five years still has the original OEM Ohtsu 22x11x8 pro-vectors. From the time I got it, if you filled both rear tires to the same pressure, it would always pull to one side. This is because one tire is slightly larger in diameter than the other, and that's most likely due to one tire having been over-inflated at one point or another.

You are looking to match the circumference, not the pressures. I had to get used to one of my rear tires being lower in pressure than the other because now when you're turning the two tires will behave differently depending on which way you turn, but I have no problem dealing with that and I'm far more concerned with the machine tracking straight.

Buying a new tire will likely help if the existing tire that you're keeping is a fairly new tire, but even still, there could still be a difference in tire diameter between the two because they're from two different batches and one has been ridden on as well as inflated for some time now.

Regardless of what you do, it's very simple to just fill one tire or deflate the other until the bike tracks straight.

barnett im not sure why your turning this into a pissing match but whatever. what im saying is if you dick around with air pressure and a measure tape even if you get it close with rounded tires which i almost guarantee is whats on the trike one tire will have a wider area touching the ground and when you hit the gas its still going to pull. Can you spend enough time doing that halfassed crap to get it close? ya you probably can but nothing bothers me more than a cob job. so ya if your ok with having mismatched psi and uneven tires i guess you could make it liveable but for me its not acceptable and im just trying to help the OP do the job correctly. I guess working on other peoples things for a living makes me that way.

And im sorry i didnt credit you for also mentioning that it could be the front. Im not trying to insult anyones intelligence but the fact is these psi and circumference measurements are cheap and not the correct way to fix the problem. Im a firm believer if your going to offer advice to someone on a forum dont offer halfassed cheap advice.

ummm...that is an assumption which is inaccurate. Rule number 1 is never make assumptions like you obviously are if at all possible.

Im a firm believer if your going to offer advice to someone on a forum dont offer halfassed cheap advice.

Well since my advice is not halfassed, it's obvious you are not referring to me, and just because you may not understand the purpose of others advice, it certainly does not mean it is halfassed either.

im not going to argue with you. bottom line is having tires with substantially different amounts of tread and trying to compensate by using psi and a measure tape is definitely half assed! maybe even quarter assed! if a customer brought a wheeler in with that problem and i offered your solution guaranteed they would give me a funny look and leave. just buy a new set of tires why cob your wheeler. its like tying up your muffler with fencing wire ya it works but its going to vibrate and wear out all the joints.
but im done here ive given my advice and thats all i can do who am i to say what you should do in this situation i mean i was already 10 when i rebuilt my first atc what do i know.

Yes, I saw that and I think you did a fine job!

This was the issue I had when I joined. It was also suggested that I check circumference. They were about an inch different. More air in one of them fixed it. So grateful for that because the tread was good and I didn't want to throw them out. Been dealing with it for 2 1/2 years and it's a non-issue.

In this case, I think Indy is offering good advice. I thank you for that! I'm going to shop for new tires, soon.

...try doing a wheelie if it rides true in a wheelie its a front end problem...

If ya think that is sound advice I got some swamp land in Florida I think you should buy.

I may just be a perfectionist lol. Idk ever since I started doing mechanics as a job 10 years ago I just like to do things right. Im not gonna lie as a kid i did some really sketchy things to my own stuff.
When i was 13 i took the cold start setup off our farms tractor (you can hook a can of starting fluid to it and it connects a fitting to the intake manifold) I hooked it up on the handlebars of my rm125 and put the hose with a fitting to the manifold and a T fitting with a smaller hose hooked to an air vent on the carb so when spraying the starting fluid it would pressurize the float bowl and add extra fuel to help lubricate the cylinder(starting fluid drys out cylinders really fast)

I see that we both at least agree that comment is funny, lol.

To the op, you should have enough information here to move forward.
