Bought a used Stolen Agent 12" for my kid. The orange tires were brown and dry, aka no grip to them. So I bought these Haro tires from Albes. The tires are too wide and I need to widen the chain stays for clearance.
Before you say to get a longer chain, that was my first idea but the brake pad mounts are already maxed out, so a longer chain won't work.
I'll be flattening the chain stay tubes where the tire rubs for more clearance.

don’t flatten the chain stay, get a narrower tire.
2.4 are overrated imo
Some light dimpling won’t hurt at all. Just don’t go too hard
Yeah 2.0 for children weight is the matter
Before I’d say to get a longer chain, I’d say perhaps a look at the old tires would have prevented you from having this issue in the first place..?🙄
Try to add a link or 2 on the chain. That should give enough room to pull back further
Way cheaper and easier to buy a skinny tire….besides we ride wide fronts and skinny back tires … wide up front for control and skinny in back to gain speed.
Oh yeah just gonna fuck up the frame on this bike where it will be taking the most force then give it to my kid wtf is wrong with you
That bike is too small for you.
You could always get an Xacto knife and whittle away the bit of tire hitting the stays. Trials riders do this all the time to make tires fit their bikes. Only cut the surface layer and only take enough off for clearance.
Steel frame builders add dimples for chainring clearance all the time, a little bit is fine. Especially on a bike for a tiny kid. You get tools for this (peen hammer I think?).
I wouldn’t do this to an adults BMX though because the 20” wheel flexes way more during riding, so you need more clearance, and the frame strength is being tested a lot more.
I obviously can’t see the old tire but if he is riding park, a lot of times park tire look like they have zero grip but they’re fine. I just have had less informed people act like my tires are awful when there genuinely brand new and sure they would be shit on dirt but that’s not there use case.
Tires like the one in the picture would actually be a hindrance in a park.
