GHOSTTE Posted February 11, 2023 Share Posted February 11, 2023 Looking at aftermarket tire options for the EX30, 80/100-14 seem pretty rare. Any thoughts on a 90/100-14 fitting? I thought the C40 was supposed to be wider than the C38 so wondering if it would fit. Quote Link to comment Share on other sites More sharing options...

Someone on Facebook mentioned that 90width doesn't fit because it hits the suspension. He mentions that 80width is the widest that the suspension will allow. 1 Quote Link to comment Share on other sites More sharing options...

Any thoughts on a 90/100-14 fitting? I thought the C40 was supposed to be wider than the C38 so wondering if it would fit. the original tire they were gonna use is a duro brand tire in 80/100-14. They said it was terrible for turning so they changed it. An 80/100 tire is still an 80mm wide tire from carcass wall to wall. The 100 was the aspect ratio so it was a taller tire for the same width They use the cst186 tire currently which is a 2.75-14 tire. Its the same tire size as the exn, sherman, RS, etc. Meaning the rim being wider doesnt actually affect the tire fitment. It just stretches the profile of the tire wider and changes how certain tires feel on a wider rim. You can put an 80/90-14 tire on the ex30 such as the michelin pilot street 2. Its been confirmed to fit and is the same size as the stock cst186. Just go with your regular sherman sized tires in 80/90-14 and 2.75-14 90/90-14 and 90/XX-14 tires wont fit Edited February 12, 2023 by Cobaltsaber 1 2 Quote Link to comment Share on other sites More sharing options...

Will need to get clarification if a 90 will fit. The 100-14 looks like the profile could be too high but again we will need clarification on this too. https://www.tacomaworld.com/tirecalc Quote Link to comment Share on other sites More sharing options...

Oh well, im still excited and the wheel should be here sometimes before March. Quote Link to comment Share on other sites More sharing options...
techyiam Posted February 12, 2023 Share Posted February 12, 2023 Also, the tire looks to be underinflated. The rim was so close to being struck by the front edge of each step. 3 Quote Link to comment Share on other sites More sharing options...

Cruiser or not, most cruises involve some kerbs and a few steps even if you choose your paths quite carefully so you'd really hope it could do the shallower of them, if not huge flights of steep ones... Lastly, would those pads have scuffed down on contact had they been stuck on with anything other than the pretend glue they ship with ?

Thats just the way the tyre deforms when you go down stairs. Check out other footage in slow motion and you will see. Quote Link to comment Share on other sites More sharing options...
techyiam Posted February 12, 2023 Share Posted February 12, 2023 (edited) I don't agree with the notion that every wheel should be able to do stairs. People who want to do stairs should buy stair capable wheels. I don't believe people who don't do stairs should pay a price of high center of gravity.

Nah the tire and suspension compress way more when hitting stairs as the contact patch is on the edge of the next stair. The tire compresses almost to the rim When riding off just a single curb, you'll land on flatground and the tire wont compress as much as its landing on a bigger area. You wont clip the kickstand this way as long as you clear the curb with enough speed Quote Link to comment Share on other sites More sharing options...

I've seen him in person and he's not that tall. Definitely under 200lbs -- probably 180ish range? I would agree that the tire looks slightly flat but you do get that effect in the tire when you do curbs. What gets me is I have the Sherman and I'm pretty sure the bars are located in the same spot as the battery on the EX30 -- I could be wrong -- but I don't get those issues. However, I don't go down stairs on my Sherman. I go off curbs all the time though. Also, consider Hsiang is an experienced rider who routinely reviews all kinds of EUCs. He likely would not deliberately make the tires flat for this I don't think. He knows what he is doing.

Paul A Posted February 12, 2023 Share Posted February 12, 2023 Might need to conduct an experiment to determine if the kickstand would make contact with a kerb. Rider weight and suspension setting might be the main factors. Quote Link to comment Share on other sites More sharing options...

Not sure it'd make that destruction on concrete if plastic? Quote Link to comment Share on other sites More sharing options...
