ZTR Olympic rims - Largest tyre?

gt-arrowhead

Hi, i bought a new wheelset during the winter, but i didnt really look at the width as i was too bothered about looking for a great deal and good reviews, and since the ZTR Olympic wheelset had both i went for it. Then i realised that the rims were a bit on the thinner side when i had my first look at them when they came through the post. I may have perhaps changed my option if i knew they were as thin as they are.

The internal width is 18mm
The external width is 23.2

I am going to be getting some new tyres around June/July for my summer riding, and i was thinking to try out a bit more of an aggressive tyre (something like a Maxxis Advantage?)- currently using Maxxis Aspens which are more biased for really low rolling resistance XC stuff. And im just wondering, what is the widest i should go for this rim?

My previous rims were 18mm, my current 20mm and I've run 2.25" tyres (Schwalbe) with no issues.

I've used the 2.25 ADvantage on 19mm rims and had no issues, it is quite tall though and I found it caused clearance issues on some Rockshox forks.

I wouldn't run more than 2.4" on Olympics, but they'll be fine up to that, may come up a bit 'tall', but meh.

Tyre sizes are sort of meaningless. A 2.25" Schwalbe can be bigger than a 2.5" Maxxis. You would have thought 2.5" is 2.5" but it's not.

Thanks for replies. I was hoping to go 2.2" or maybe 2.3" if funds allow. The "bigger" tyres are usually more expensive (aiming for £20 a tyre max)

Yeah i know sizes can vary but they are usually give or take the same.

Im thinking about a High Roller or an Advantage.

You're likely to run into issues with the rims being tough enough for the sort of riding that justifies big tyres before the tyres themselves specifically become an issue!

I ride XC with the odd downhills which have some roots, if my old school v brake rims can handle the abuse on a rigid bike, with no troubles, i have ever confidence in my Olympics.

You don't need to go bigger than 2.25" from what you say, and you are better off with a good tyre than a wider tyre that is less good!

A bit of shopping around and I can usually pick up good used tyres for the right price.
