Review: Quality tyres - Always used to buy the ultra II and these are just as good. Went on easyish. Roll well and so far wearing well. Grip as good as the old model.
Review: Fewer punctures,hard wearing. - I can only say how pleased I am because I've had fewer punctures ( 'flats' for those unfortunately in the USA!) whilst using these on my inexpensive road bike which is used for 6 miles daily. A good wearing, reasonably priced, quality tyre in my opinion. Dispatched by a very helpful seller. Thank you.

## Questions & Answers

**Q: Will it fit 700x25c?  It’s a 28x15/8x1**
A: Check Google. 28 is sometimes advertised as a 700cc size. Good luck

**Q: Will it fit 700x25c?**
A: Yes

**Q: What is the difference between 700x25 and 700x25mm?**
A: The "25" is the same as "25mm", which is the width of the tire.  No difference.

**Q: My previous tires say 700x26c. Will the 700x28c fit?**
A: If you have some clearance between the tires you have on now and the brake calipers, they will fit fine.  I went from a 700x25c to 28's without issue.   The larger tire rides much better too.
