I just put a 24 x 3 Gazz tire on my Torker DX. I used the orginal stock tube that is 24 x 2.125 – much smaller than my new tire. I have only played around a little in my driveway so far and like the air pressure at about 16 psi which is the bottom of range (15 to 25 psi) suggested on the sidewall.
Since I’m using a smaller tube, do I need to use higher pressure to take up extra space inside the bigger tire? Do I have an increased risk of the tire coming off the rim if I go out on the trails?
BTW – for those who have asked in prior threads about the clearance and received mixed answers – I bought my DX about 4 or 5 months ago and there is 1/8 in clearance on each side of the Gazz and about 1/4 in clearance at the top. As currently mounted, the tire measures 25 7/8 in diameter.
Chances are you shouldn’t have a problem using the smaller tube in the Gazz. When I was still racing motorcycles offroad, we would use a 4.50 tube in a 5.10 tire at around 12 psi. without any problems. I’ve also used 1.5 tubes with 2.3 tires on my mtb. The Gazz has a pretty beefy sidewall and should hold up well at 16 psi.
I run only 18 psi in my Gazz and weigh about 185
I used a 24 x 1.5-1.75" tube in my 3" Gazz for about a year no worries. Over that time there wasn’t a single flat. Maybe I’ve just ahd bad luck with the 3" tubes, but in my experience the tube size has made no difference. A smaller tube is cheaper and lighter.
As for the rim – Yes, I am using the rim that came with the DX. The sidewall of the Gazz says the minimum rim width is 28mm. I think this DX rim is exactly the minimum 28 mm, if I measure the outside of the rim. I don’t know if this measurement is supposed to be the inside width or the outside width of the rim.
As for the 20 in Torker –
I looked at the Creepy Crawler, but the 20 in is only 2 in wide. Which is not as wide as the 19 x 2.5 Creepy Crawler. So, I didn’t think it would be as good. Agree or Disagree?
I can’t really find a good wide tire alternative for my Torker 20. Since I’m not really interested in doing trials, but want to use my 20 to learn new skills, I would rather upgrade the Torker 20 tire than buy a real trials uni.
I have been looking through the books at my LBS and found a tire named “Flame” that comes in a 20 x 3 size. It’s not the Kenda Flame. I think it was called Pyramid, but I’m not sure. The LBS is going to try to order it tomorrow. If anyone is interested, I’ll let you know what they say.
