When are you supposed to know when you are change your tires? When the tread is bald without any spots in the middle of the tread.

 

i change mine when they won't hold air, and the plugs want to fall out. and when i say won't hold air, i mean 3 cans of fix of flat and it still is flat within 20 miles, my tires were way past bald

 

Well, I really don't want to keep mine on my atv for that long.

 

Do you think I should get my regular Ohtsu tires. I want to keep it less than 50$

 

Go to your local dealer say I want the cheapest tires you got in this size, put whatever on if you are just getting rid of it.

 

I want to get a good quality tire that is also somewhat cheap.

 

Before the first ride!

On most quads and dirt bikes, the stock tires are pretty lame. They are often there to meet a price point, and not because they are the best choice. On most of my quads, I change out the rubber before I even take the first ride. The exception is my Ranchers and the TRX90, where I have kept the stockers and am happy with them.

I know, you are asking about when they are worn out. When worn, I would change them early if you can afford it, but if money is an issue ride them until they aren't giving good traction anymore.

 

I can get tires whenever, but i just want to see what i can get at, say, 55$ or lower.

 

Now I have a new question. Does it matter what size of tire you put on a 300ex

 

I ride both desert and mountain woods trails, so on my big sport quads I am running ITP Holeshot XC's, size 22X7-10 front, and 20X11-9 rear.

It has been 10 years since I owned a 300EX, but as I recall it came with very lame 22" tall rear tires. I gave up a little ground clearance when I went to the 20" tires, but liked the increase in stability and lower effective gearing.
