Add Sound Insulation to Tires?

[HeyEph]

I have an opportunity to buy some mint used Continental ProContact tires in 255/45R19 to fit my Model Y. But, they are NOT from a Tesla, so they don't have the insulation. Can that be easily added?

I have read that there isn't a noticeable difference between tires with insulation and tires without. Your personal experience may vary.

The sound insulation is a layer of foam pasted inside the tire. If it is not fixed properly or if it opens after some amount driving it will create lot of issues. I advice is don't do it yourself, ask a tire shop if they can do it as they know better and are more knowledgeable about if it can be done or even should be done at all.

I don't think it can be added but I also don't think it makes much difference. I changed to non-foam tires within the first 400 or so miles with my Model Y so I couldn't really tell you how much difference it made for my Model Y. I CAN tell you that we went from Michelin Primacy tires WITH foam on our Model 3 to Michelin Pilot Sport AS 4 WITHOUT foam and it made no discernible difference.

I don't think you'll notice much, if any, difference going to the non-foam tires. I certainly wouldn't try to add it or pay a premium for tires that have it.

Screw the foam, do not want.

honestly got new michelin pilot sport a/s 4's and they are quieter than the stock continentals without foam in the tires

You have to make sure it's an EV-rated tire so it can handle the heavy load and also not impact range.

Like the last poster stated it must be an XL load rating or you will have problems in a short time. I changed from the stock Continentals with foam at 42000 miles and went to Michelin Cross Climate 2s without foam. After a couple thousand miles the tires worked in and the noise level isn't much different from the stock tires.
