How to choose road bike tyres
Start with your wheels, frame clearance and usual routes. To find the right tyre, compare size, fitting system and tyre characteristics: the best model is the one that meets your needs.
700x25, 700x28 or 700x32?
700x25 road bike tyres have a narrower nominal width than 700x28 tyres. The latter can offer more comfort on uneven tarmac at a suitable pressure. 700x32 tyres are an option for those seeking greater air volume, if the bike and rims allow them. Actual width also depends on the rim's internal width.
- Check the ETRTO size: 25-622 corresponds to the designation 700x25, while 28-622 indicates 700x28.
- Check the limits specified by the frame, fork and wheel manufacturers, including clearance around the brakes.
- Choose the pressure according to total weight, tyre width and surface, keeping within the tyre and rim limits.
Inner tube or tubeless ready?
A tube-type tyre requires a compatible inner tube. A tubeless ready tyre can be fitted without a tube on compatible wheels, using suitable tape, valves and sealant. On hookless rims, use only combinations expressly approved by the manufacturers.
You can compare the Continental Grand Prix 5000 700x28 with the Grand Prix 5000 S TR 700x28 Tubeless Ready: always check the version on the product page.
Compound, casing and use
The compound affects grip and wear; the casing and protective layers contribute to comfort and puncture resistance. A folding bead makes an unfitted tyre easier to carry, but does not by itself indicate tubeless compatibility. For frequent training, consider durability and protection; for racing, also consider rolling resistance and weight.

Frequently asked questions
Are 700x25 or 700x28 road bike tyres better?
It depends on bike compatibility and use. 700x28 tyres can offer more comfort on uneven tarmac at a suitable pressure; check your rims and frame clearance before choosing them.
Do 700x25 and 25-622 indicate the same size?
Yes, they are two designations for the same nominal size. The ETRTO designation 25-622 indicates the nominal width and rim bead seat diameter; fitted width can vary depending on the rim.
Can I fit 700x28 tubeless tyres on any wheel?
No, you need compatible wheels and tyres approved for that setup, as well as suitable tape, valves and sealant. For hookless rims, specifically check the compatibility stated by the manufacturers.
What are the best 700x25 road bike tyres?
The choice depends on the surface, frequency of use and your priorities for rolling resistance, grip, durability and puncture protection. Available models include Continental Grand Prix 5000 700x25 and Vittoria Zaffiro IV 700x25c: compare their features on the product pages.
What pressure should I inflate road bike tyres to?
There is no single pressure for everyone: consider total weight, actual width, surface and whether you use inner tubes or tubeless. Follow the manufacturers' guidance without exceeding the tyre and rim limits.
Can I switch from 700x28 tyres to 700x32 tyres?
Only if the frame, fork, brakes and rims allow that size. Also check the actual fitted tyre width and the clearance required by the bike manufacturer.
