Hi guys,

 

Its nearing the time for me to buy a new pair of tyres. Its my first time using tubbies so would like to know what decent brand of tyres I should go for that will last long and won't make a huge hole in my wallet.

 

Any help will be appreciated.

You want durability, quality and low cost? Talk about wanting your cake and eat it.

 

Tubbies can be had for about R340-00 a pair, at the low end. They're pretty decent but you cannot remove the valve core to fit the better type of valve extender. As the price goes up, they become lighter - thus thinner and less durable, but with added extras like removable valve cores.

 

However, it sounds to me like you have clinchers and are now considering fitting tubbies on those same wheels? No? Cant be done.

What wheels do you have? If you whant cheap, then buycycle has ritchey tubbeys for around R180, they are desent enough and if one pops its easy to replace. But like Johan said, do you have clnchers or tubby wheels, coz your OP can be misleading.

OK, this is from someone who rides clinchers.

Is the ride that much better on tubbies, to warrant the added aggravation of changing a punctured tyre and the exorbitant cost of replacing?

No.

 

I went from high quality tubbies to high quality clinchers and I can't say I notice any difference.

 

Rolling resistance values for good clinchers can be the same as those for good tubbies:

If the answer is no, then why ride tubbies?

 

Weight is the only advantage. And weight saved on the wheel is more important than weight saved elsewhere, although how much more important is a topic of much debate.

They're lighter e.g. Zipp 404 carbon clinchers are about 300g heavier than the tubbies.

 

There's an argument that on really long descents there're fewer problems with rims overheating, causing tyre failure.

 

On very smooth road surfaces, tubbies will have a lower rolling resistance since they can usually be pumped to a higher pressure. The rather scarce info out there seems to indicate that you get diminishing returns when you go above typical clincher pressures on most normal road surfaces, though, so it's not usually an advantage.

 

They're less prone to snakebite punctures on very rough surfaces (like cobbles).

Tubbies is for racing only and they wear quickly, but it is light and fast.

I use Stan inside tubbies to help to prevent punctures, but it can be messy!!

 

I use tubbies on racing carbon wheels and I use cheap tough tyres on training clincher wheels...

biggest advantage with tubbies in my opinion is the weight, tubular rims are generally lighter (by up to about 200 grams) than clinchers. As for the rolling resistance etc... thats a whole debate on its own and has been covered on thehub and internet in great depth.

Just have a decent no.2 before the race and there is your 300g weight saving. :P

On the other hand, get tubbies, do the no.2 and save 600g. Unless tubby owners are anally retentive... :P
