Mac 3 stroller has a flat right tire.

Most strollers use the same tires and tubes as kiddy bikes. 10" or 12" your local bike shop could help. I buy spare tubes and tires from Kmart.

look and see if there is a lil rubber plastic cover in the middle of the tire and press on it might be a release button to unlock and pull off the tire / thats how mine works. if that dont help u can just take the whole stroller to a bike shop and they will fix it for u

Just below where the handle bar part meets the rest of the frame, on the left and right side you will find black plastic bits that point down, which you can slide your finger behind. The right hand one has a silver button which you need to push in. Then pull both of the plastic levers towards yourself and push down at the same time. The Mac 3 will then fold down.

Any bicycle shop will be able to repair the tires for you.

Check your tire pressure. We just experienced this a week ago. Sure enough, the right rear tire was flat. Once the tire was pumped up, it no longer pulled.

gas stations or tire places can often help fix a bicycle tire-- why not a stroller tire? shoudlnt cost more than 5-10 bucks.

if just a slow leak, you can also try a can of fix-a-flat from the auto parts store-- pump it into your tire when somewhat deflated, walk it around to let the inside get coated with the material, and then inflate it to proper levels.

I advise you try the shop where it came from for a replacement tube for it.

Failing that, 'phone the manufacturer to have one sent out.

If purchased in Canada call Dorel Juvenile Group customer service dept - toll free 1-800-544-1108. They will require the model number and date of manufacturing which is located on the back of the seat of the Quinny Freestyle. They will then ship the tires directly to you. I needed to replace my two front tires on my stroller and with shipping and taxes it will we $22, the tires are $8 each. I should have my tires in five to ten days. Plus the customer service representative I spoke to was polite and very helpful.

Any bike shop will have patch equipment. You need to deflate the tire and remove it from the wheel. See if there is a tube inside the tire. If so, the fix is easy: either purchase a new tube for the tire, or get a patch. Use modelling glue on the patch then press it continually on the hole on the tire for about five minutes until it is dry. Afterwards, re-insert the tube into the tire, reattach the tire to the rim and pump it back up

The following is from the instruction manual for the Expedition LX. It should be very similar to the Expedition LE.

"Stroller pulls to one side:1. The stroller is sensitive to the air pressure in the tires. If the rear tires do not have equal pressure, the stroller will feel like it is pulling to the side with the tire with the lower tire pressure. Check that the rear tires have the same pressure. Add air pressure to a maximum of 25 pounds using a bicycle style hand air pump.2. The alignment of the front wheel of the stroller can also cause the stroller to pull to one side. The stroller is designed so that the front wheel can be adjusted to correct for any alignment problem. Page 3 of the instructions
shows an expanded view of the front fork assembly. To align the front wheel, first loosen the wheel via the quick release handle as in step 2 of the instructions. Grab the front wheel directly in front of the stroller and push the wheel in the opposite direction of the pulling problem. You will notice that the axle will move within the slot on the fork. Move the wheel to the side a small amount. Retighten the quick release handle. Give the empty stroller a push across an empty smooth surface (let go of the handle) and note if the stroller now runs straight. Re-adjust the axle a small amount at a time until the stroller runs straight. Please note that a very minute
movement of the axle will affect the tracking of the stroller. Once you have aligned the front wheel, you can mark the holding plate position with a marking pen if you detach the front wheel on a regular basis. Please note that the hole in the fork is designed to allow the stroller to be adjusted to pull to the right, go straight, or pull to the left. If you continue to have difficulty with tracking, please call our customer service department at (800) 328-7363 for assistance."
