I put the Pirelli Diablo 150/70/14" on my Mp3 400 as suggested on this site and it rubs the shock absorber on the right side but there is ½" clearance on the left. The old tire I took off wore out on the left side. They told me at the Dealer it was because of the crown in the roads that cause the tire to wear on that side. When I showed them the new tire not being centered between the shocks the owner told me I should not have put the larger tire on the bike and he would not address the issue. Has anybody had any problems like this?

I had a similar problem although not on my MP3. One of the spacers (washers) was on the wrong side. When I put it where it really belonged it centered the wheel.

Show him the "Super Size Rear Tire" thread and how many others have done it. Note we have done it with 400s, not just 500s including me.

I would have guessed what Larry8 said too. Check the spacers.

When the dealer saw that I had another shop put the new tire on he told me he would not work on the bike anymore and that I should not have put the larger tire on. I called Piaggio and they said I must put the right size tire on the scooter. I am currently waiting on another tire to come in but it will not change the fact that the wheel is off center and the old tire wore out on the left side. Brad at Piaggio doesn't seem to be too understanding of the situation. I think I need some help on this one, Does anybody have a suggestion?

remove the wheel and check the spacer (or washers) length. You may have inadvertedly reversed them.
Since quite a few other people have succesfully installed that size tire, there must be something wrong with your setup.

The old tire wear is another problem. Could be some sort of defect in the tire, or a misaligned shaft. Or even a worn wheel bearing.

Both lower rear shock mounts should have a kink in them - and both should be in the same direction - to the right (on the 500 at least, I'm assuming the 400 has an identical arrangement). They should NOT be 'symmetrical'. If that's OK, then someone has got a spacer in the wrong place on the rear axle.

The shop that put the tire on said he thought everything looked ok when he put the wheel back on. It makes perfect sense that the spacing is incorrect and you sound sure that there are spacers on the axel. I will tell them on Tuesday when the shop opens to please check the spacers to make sure they are installed correctly. Thanks once again

On my MP3 250 there is this cone shaped spacer as you mentioned but I think if one were to put it reversed one cannot fit in the brakes later. I once did that and found out that the brake won't fit into place. Opened it and turned the spacer the other way and the brakes fit in without any problem. BTW, the cone shaped spacer I mentioned goes right into the shaft that is holding the tire. Hope this helps.

Mp3 400 rear tire issue
If sanyone is still interested the only thing I can say about this situation if this scooter were a horse I would have steaks in my freezer. The dealer resfused to look, repair, etc,etc, the bike. He said because i had someone else put the rear tire on he will no longer work on my bike, this is Florida Motor Ssports of Tallahassee. So I took it to the Jacsonville, fl dealer, Jacksosn said yah we put that size tire on our mp3's all the time it should fit. So the first thing they checked was the spacers and they were correct. So instead of looking for a problem with the bike they continued to look at the tire. They made the determination that the Perrelli tire was miss labled at the factory and it was wider than the tire should have been. Keep in mind they are still not addressing the problem of the tire NOT being centered between the shocks as the pictures shows. So they call me on the phone and said we will just put one of OUR perelli tires on of the that size and everything will be OK. Great, I drive back to Jacksonville one week later to pick up the bike only to find some off the wall brand cheap tire on my scooter. "Oh, we didn't have a perrilli and it would have taken weeks to get one. The tire did not rub the shock and it was the same size as the perrilli but it was still off center by a half inch. Piaggio keeps telling me they are going to do something about it, send a tech to look at it at the same time they are trying to worm out of it. Bottom line, this scooter is a piece of junk that Piaggio nor the it's dealerships will stand behind. As far as the Perrilli tire goes, at Perrilli's request I returned the tire to them for inspection several weeks ago and have not heard from them.

all the 400 and 500 are more to the right side even with the stock tires. Go look at new ones on the showroom floor and take a tape measure with you to measure the clearances on both sides. The 150/70 is closer to the right shock but there is no issues if installed correctly. have a look at the manual and remove the wheel yourself and reinstall. Just cause they say its ok don't mean it is. Oh the old 150/70 you did get it back right. If you are loking to sell it you can post it here in the for sale section.

I also have the same problem. I posted pictures on another link, but can't look it up right at the moment. As OAD said, the stock tire was not centered between the shocks either. I assumed that the reason my tire is at the right shock was because of the shape of the tire (it is a metzler tire).

OAD, one day I'll ride over to your place and show you how it looks.

I'll be heading to Albuquerque this weekend so I can't go. My son wanted to ride also but don't know how to squeeze it in.

I may be able to head over to your place MT or W. I'll send you a PM as soon as I can check my work calendar.

I've just gone outside and checked my Fuoco. That has the rear wheel 4mm nearer the RH shock than it is to the LH shock. Conclusion - the shocks are not equidistant from the centre line (one 2mm nearer, one 2mm further away) rather than the rear wheel being off-centre.

Figures for my 150/70-14 MGS are a gap of 6mm on the right, 10mm on the left. The Diablo may well be a bit wider than the MGS, which would account for the rubbing. Identically numbered tyres do not necessarily have the same maximum width.

I believe that different tire manufacturers may have different widths because the profiles of the tires are different. My Metzler is just about against the right shock. I figured it would be educational to look at my tire next to OADs pirelli to see if the issue is the tire or the install.
