700x30 - much difference vs 700x28 ???
 

I have a used 2016 Scott Solace Premium on the way to me (got a good deal, couldn't resist). This will be used for casual road rides and commuting to work. Its an XXL and I'm a tall/big guy, so I'm wanting a big volume tire. From what I've read, I can fit 30s on it. My question is, are there any 30s that will give me any advantage over the more common 28s? I'll be on pavement 95%, but it might be rough pavement, and some pretty smooth gravel/dirt trails when they're dry.

Thanks in advance.

Is this size much of a thing yet? I didn't know there was much between 28 and 32; options are likely a bit limited.

My guess would be that with around 7% more air to squish, you'l notice a difference over 28s - not huge, but noticeable.

A much bigger factor is one tire model compared to another tire model. A 2c difference is relatively minor compared to what one model tire at some pressure can offer over some other model. There may be a 30c tire (are there 30c tires?) that may feel like a frozen garden hose compared to a different model 28c.

I'm using these now, and couldn't be happier with their performance. Right now they are about $40 each

They exist, and they are marvelous

+1 Is there much difference between a 560 pound bear and a 600 pound alligator? Note also that tires are often not exactly the claimed width. The variation off claimed can be different for different sizes of the same tire, never mind, different manufacturers.

Probably your best bet - first measure the width of your tire. Buy a tire that is 2 mm bigger than what you measure from a shop under the condition that it is advertised size and you can return it if it is not. (If they don't want to do that, ask them to mount it on one of their rims of similar width and measure it.) Do take into account that tires stretch with inflation time so an old tire will be significantly bigger than when new. (The amount of stretch is not the same for different tires.) In short, this is not an exact science.

And as said above, the tires themselves can have differences in feel by construction that are larger than differences in tire size. I promise you that Vittoria's Corsa G+ in 28c are a lot more comfortable than many 32c or even 35c tires. (Cost twice as much too.)

Yeah, once you have enough air to avoid pinching the tyre, size doesn't mean a whole lot compared to how supple the casing and tread are.

i recently went from a 700x25c to this tire ^^ (schwalbe g one speed 700x30) and I am in love with them. I've mounted them tubeless and run about 65psi. they roll extremely well, even compared to the Schwalbe pro ones, are very comfortable, traction is great and haven't had a puncture yet.

I Inflate them to 55/60psi f/r, and love the smooth ride

Zero punctures in 2800 miles. Threads were showing on the rear tire, so I replaced it with a new one. The front still looks like new.

$40 at Merlin Cycles is a great price.

Add me to the list of G-One Speed lovers. I've been running them exclusively for a few years, now. In fact, when I bought a new bike last year, one of requirements was that I could fit these tires.

Conti 4000 28
 

measure just a bit over 30mm on my A23 rims. nice.
