How to fix loose valve?

I presume that the tire is very flat at this point. You'll have to hold the valve in position with one hand while you get air in it, holding the chuck with the other hand. Once it reaches a minimum ...

How to tell when it's time to give up on tires?

Short answer - if you wouldn't feel safe riding on the tyre yourself on a high-speed descent, then it is for the bin. Add a mental safety-factor/margin of error of 20% and don't be hesitant to say &...

For reference - tire parts names. The "Anti-puncture strip" and "bead protection tape" are not found on most tires. Bead, casing, sidewall, and tread are the most common ...

How to tell when it's time to give up on tires?

This is a great question and there are actually some good ways of approaching it. Inconveniently, you need to see the tire installed and inflated to have high certainty that it's good for reuse. Until ...

Safely seating tyre beads during seasonal installations

Note: this answer mainly concerns fairly tight-fitting tubeless-style tires on tubeless-compatible rims. Personally, I like to use soap as a tire seating aid for difficult tire+rim combos. Bar soap is ...

How to tell when it's time to give up on tires?

This is tough to answer as it'll be different for different types of tires. For my riding styles, a tire is shot when the side walls won't stop weeping (all bikes), when the knobs stop hooking up (MTB)...

Can I replace 26 inch tires with 29 inch tires on my Giant Sedona?

I cannot comment on the resulting dynamics and riding quality of such a bicycle, but yes you can (however I feel the question is "if I can, should I?") You can change the fork on your bike, ...

If I want to later mount this same Swytch kit on my Giant Sedona that has 26 inch tires at present is there enough space on the Giant Sedona to accomodate the larger 29 inch tire size? Almost ...

Can I replace 26 inch tires with 29 inch tires on my Giant Sedona?

If they are disk wheels, it may be remotely possible. If not, no, the rim brakes in the wrong location. 29" is much larger than 26". Being the front fork, its possible, but unlikely a 29er ...

Can I replace 26 inch tires with 29 inch tires on my Giant Sedona?

You cannot just mount a larger tyre, even if you had the clearance. The larger tyres need also need larger rims, that usually means you need complete new wheels. It is unlikely that a frame for a ...

Is it safe to ride after innertube bulged out (returned to normal after deflating)?

I agree with the other answers that if the inner tube is still intact, it's fine to reuse. The inner tube holds the air in. The tire holds the inner tube. A tire that bulges is damaged. Discard the ...

Is it safe to ride after innertube bulged out (returned to normal after deflating)?

You probably pinched the tube between tyre and rim. If it still holds air there should be no permanent damage. I’d deflate everything, then make sure the tyre is seated properly. What I do after ...

Is it safe to ride after innertube bulged out (returned to normal after deflating)?

The tube holds the air, the tire holds the pressure. A bulge is entirely a failure of the tire. If the tube remained intact then the tube is fine. I would not ride a tire that had bulged as you ...

Is it safe to ride after innertube bulged out (returned to normal after deflating)?

If your inner tube didn't pop/rupture then it is fine to reuse. Instead, your tyre's bead/hook failed to maintain its grab on the rim. Either it wasn't located right before you started inflating, or ...

Tubeless 29r tire develops cracks without air

I think you just got unlucky with some particularly thin sidewalls. It does not look like intentional damage from humans or animals - the sunlight may have had some accelerating effect, but that ...

Would you ride with this tire with cuts in the sidewall?

Yes, but only to the nearest tire shop. While doing so, put the tire boots in your emergency tire repair kit to the inside of the tire, at the areas where the cuts are. Tire boots weigh next to ...

The most commons ise is 700C/27"/28", but here are smaller sizes that you may come across. As I said in a comment to another answer, I had a bike with tubulars and was sold a tire that ...

How do tubular sizing standards actually work?

I've got one 80's bike with tubulars, and it was a learning curve that ended with buying some clincher rims for everyday rides. AFAIK all tubular tyres are 622 and 630mm capable. The difference is in ...

Letting air out of tires in the rain: any chance of water getting in? (Presta valve, tubeless tires)

Just mentioning this as a point of interest - there is zero chance of this being of practical concern. I just think it's neat. Water vapour, if present, would absolutely have flowed "upstream&...

Letting air out of tires in the rain: any chance of water getting in? (Presta valve, tubeless tires)

No risk. 70psi is about 5 times the atmospheric pressure. Most sealants are also using water as main fluid (or water/ammonia), unlikely that the small quantity that may get in will have a significant ...
