Quick Summary
The YunSCM Foldable 700C Bike Tyres are a 2 pack of 700 x 40C bicycle tyres, also given as ETRTO 42-622. They are described as compatible with 700 x 38C, 700 x 39C, 700 x 40C, 700 x 41C and 700 x 42C wheels, so the key check is that your wheel and tyre size match the stated fit range.
The tyres are foldable and use soft wire technology, which matters if you want a tyre that can be stored or carried more easily between uses. The stated inflation range is 40-65 P.S.I. (280-450 kPa / 2.8-4.5 BAR), so the correct pressure setting is another important check before fitting and use.

What to Compare Before Buying
- Size: This is a 700 x 40C tyre with ETRTO 42-622. Compare both markings with the tyre and rim size you need.
- Pack quantity: The pack contains 2 tyres, so check whether you are replacing one tyre or both.
- Fit range: The stated compatibility covers 700 x 38C to 700 x 42C. Make sure your setup sits within that range.
- Inflation range: The stated pressure range is 40-65 P.S.I. Compare this with the pressure your wheel and tyre setup requires.
- Foldable format: If storage or transport matters, the foldable design is a relevant choice factor.
When to Consider a Different Option
Choose a different tyre if your wheel needs a size outside the stated 700 x 38C to 700 x 42C range, or if you only need one tyre rather than a 2 pack. The tyre is also described as not completely symmetrical, so buyers wanting an exactly matched appearance should check that detail before choosing.
Before You Decide
Confirm the 700 x 40C size and ETRTO 42-622 marking before ordering. Check that you need a 2 pack, and make sure the stated 700 x 38C to 700 x 42C fit range matches your wheel setup. If foldable tyres matter for your storage or carrying plans, that is another point to confirm.
