I bought a pair of new Vittoria Rubino Pro II tires and cannot install them on my Araya CTL-370. This may be the worst tire/rim combination because I've tried to install them without the tube to see if it can be installed but I'm far from being able to put the bead into the rim. I just can't get the last 20 degrees in.

It's a old rim (late 80s), perhaps they had slightly different sizes back then? I don't know. It just seems like the tire cannot be installed.

I haven't brought it to my LBS yet because I want to get it on myself.

Any advice?

Check the size printed on the old tire vs the size printed on the new tire?

They're both 700c.

Some tires are a b!tch! I've had lots of fun with Gatorskins and Armadillos. I just bought some Park Tool TL-5 levers. I used them today for the first time and these babies are serious!

Also, Kool Stop has a Tire Jack I may get if I ever run across a tire that the Park levers can't handle.

Brake goop on the rim increases friction noticeably. Take the rim and some 3M nylon pads with some soap and clean the edge and braking surface thoroughly. Mount tire as much as possible and apply liquid or
soft soap to the rim edge to lube the final bit. It has worked for me. The Park shop tire tool is also
helpful. OTOH not sure I would want to mount such a tire, the horror of trying to dismount it 6-12mo
down the road 40mi out with plastic tire tools would dissuade me. Went through this with some known
oversized Velocity 406 rims in '00. Try the tires on some other (suckers) rim just for grins. Or better,
if possible return the tires.

The Kool Stop Tire-Jack works like a charm. As does the one from VAR - which are scarce in the USA, but I like them better. Here's a link to a seller of the VAR Super Tyre Tool:

You only need one of either of these.

On difficult tires I have had to use wide tire levers such as Pedros, sometimes I use C clamps on my workbench and tire to prevent unravelling, and sometimes an automobile tire polish or a bike frame polish will help.

The Kool Stop or VAR will pull the tightest, meanest tire alive up and over the rim and seat it. They work like magic.

do you really want to carry a Kool Stop Tire Jack with you when you ride? If that's the only way you can change your tire when you have a flat on the road, I would strongly recommend different tires. I couldn't mount Conti 400's on the same rims that easily take Vredestein Fortezza Quatros- - -both 700c, same wheel that used to take Conti 3000's. . .some just won't mount and roadside flat repairs aren't fun when you can't get the tire off and back on. . .

1. When putting the second tire bead onto the rim always start opposite the valve stem because the tube by the valve stem is a little thicker.

2. Work in both directions as far as you can.

3. When you get stuck, hold the tire vertically in front of you with the valve stem nearest the ground. Pinch the tire beads together at the top to be sure they aren't seated.

4. Now grab the tire at the 9:00 and 3:00 positions. Try to push it straight down. What you are trying to do is to concentrate all of the slack in the area of the tire that has yet to be seated onto the rim. Slide your hands down and try to force the remaining bit of tire onto the rim.

MOST times I'm able to install the tire without using any tools. (I have been known to cheat.) Using a similar reverse process, I'm also generally able to remove a tire from the rim without using tire levers.

Is the VAR small enough to put in a saddle pack? It's hard to tell from the photo

Panthers007

Yes - the VAR is much more compact when compared with the Kool Stop Tire Jack. It measures 5 1/4 inches by 1 inch by 1 inch. Easy fit in most any bike-bag. Or a shirt pocket. I carry one on each of my bikes. No more metal rattling around.

I just ordered a VAR tool, hopefully it's as good as everyone says it is! The last time I tried to put on tires I thought I was going to have a nervous breakdown

Do give us a review. That guy in Texas ships Priority Mail. You should have it in a few days.

As was said some tire/rim combos are a *****.

Couple things:
1) Pre-stretch the tires. Mount them on the rims overnight without tubes. Take a set of plastic tire irons and using them upside down, pull the tire bead over the rim lip by hooking the iron on the rim.

2) Also try initially pre-stretching by hand: With sneakers on stand on the tire and pull up, stretching it like a big rubber band. Rotate the tire and repeat several times.

3) lube the rim with soapy water or baby powder. I use baby powder and always pre-treat the inside of the tire and the tube with it so it doesn't get bunched up inside when inflating.

4) Get the Park TL-10 and lube the business end. https://www.parktool.com/products/det...=17&item=TL-10. Works okay, especially if you are doing many sets of tires, but if only one set, then plastic irons are just as good.

I agree. I have a Park Tool TL-10 for my shop - but wouldn't dream of carrying "the beast" on a ride. Unless I had a support-van pacing me. LOL. For those tires that hate you, the VAR is my carry-tool of choice.

It has not been mentioned yet, and is less likely, but if you have trouble putting other tires on this rim, or if this is the first replacement, check the rim liner to make sure it is not too thick. The tire beads should seat into the deep center of the rim while installing the tire.

Panthers007

This would be a good time to examine the rim. If you're using Velox rim-strap, it can be removed - carefully - and then check around each eyelet for any cracks. Basically give the wheel a physical. Then put the Velox back in place.

If you're not using Velox, this would be a good time to pick up some. Most would agree that it's the best.

I just use some steel core tire levers to install and remove 700x25 and 700x28 conti gatorskins on my road wheels. The portable, compact version of the kool stop bead jack works OK but the big, bulky black version of the Bead Jack works even better.

Filtzer Shop Tire Levers worked great mounting conti GP 4000's on an old wolber rim. Kevlar bead seemed easier than wire, at least for Conti.

It might make fixing a flat 1000X worse than it is already.

Panthers007

Due to the issue of bulk, the OP has ordered the VAR - which is quite small and lightweight. Easy to carry and use while on the road. I do recommend tires with a Kevlar belt, such as Conti Grand Prix 4000 S tires. And Gatorskins. Close to bullet-proof.
