Hello I bought a road bike about a year ago, the tyres are very thin my mate said 23’s and I should get 25 or 28. All new to me, any advice on a set for £50 max? I tried his bike and it felt more stable.

Merlin have on offer the Michelin pro4 service corse atm. Two tyres along with tubes for just under fifty quid. Used them over summer and really rated them. They do come up quite big though, I had 25’s on mine but they were more like 28’s compared to other brands so tyre clearance on your frame might be an issue:

Now winter is on its way (as well as all the hedge trimming that’s going on now) something with a bit of puncture protection might be a good idea.

Only available in 23’s at merlin atm but like I said they do come up big so I reckon they’d around the same as 25’s compared to other brands.
If your prepared to pay a bit more I’ve just fitted these onto my bike:

Early days but impressed with them so far. I went for the 25’s and they do come up smaller than the pro4’s. Good grip with seemingly good puncture protection. Have a look round the interweb for tyre and tube bundle deals, somebody somewhere has generally got these on offer.

What make and model bike? The size will be on the sidewall of the tyre so worth double-checking. Some bikes might not take a 25 (rare) others won’t take a 28 (common), due to clearances (have a look around your tyre for current clearances (or some people here can probably confirm what tyres will fit once we know the make and model).
As for tyres, personally I’d go for Schwalbe Ones from Merlin for close to your budget (£26.50 each from Merlin or Wiggle).
Bigger tyres will give you more comfort and slightly faster rolling but the stability you felt was probably more to do with the difference in geometry between your bikes.

Thanks for the replies. I have posted a link to the spec. Mine is standard I haven’t upgraded anything yet. Really want to get into more road riding and commuting on it, currently using my mtb while I hardly use the road bike. I always feel like I’m going to snap it but then I started out in dirt jump and my other bikes a BFe. This is my first road bike.

Assuming the 105 version has the same frame, it seems to have trouble with some 28s. Probably best to stick to 25s unless there’s a shop nearby that you can take em back to when they don’t fit…

25’s are fine in that frame. The Lugano tyres aren’t bad, but they are low spec and wire beaded. I’d second the Schwalbe Ones in 25c. They are light, roll well, have good protection and come up pretty wide compared with some others. Having both 23 and 25c Schwalbe Ones, there isn’t a huge difference to be honest.

Teen1’s CAAD8 is rocking Green banded Schwalbe Ultremos to compliment that frame. The Ones are better in many ways.

As ever, road tyres are about priorities.
Fast, feel great but fragile – Veloflex Master (these are my go to summer bike tyres)
Bit more durable but still pretty fast – Conti GP4000, Michelin Pro4
Grippy, durable but not mega fast – Vredestein Senso Xtreme (these are my go to winter bike tyres), Conti Gatorskins (horrible tyres but lots of people seem to like them).
Heavy, stable but slow – Schwalbe Marathon Plus.

Fast, grippy, incredibly smooth and “planted”, with average puncture protection: Veloflex Open Corsas, £52 a pair from Ribble.

Thanks will look at these options now.

I like duranos in a 25, but then I really dont like punctures. Fine them fine for grip and longevity
