Changing from OEM 18" to OEM 20"

Hey guys, I currently have a 2014 Grand Cherokee Limited with the OEM 18" wheels on it, and am going to be purchasing the OEM 20" wheels with the Goodyear Fortera tires that come on them.

The tires already have the TPMS and center caps on them. I am planning on taking to my local shop to get them changed out, but am wondering if I have to do anything special since the rim sizes are different? I know that the tires on the 20" are smaller than the 18"s, however I do not know if it will make a difference for the odometer/speedometer.

So basically my question is, do I have to do anything special such as taking it to the dealer in order to change something, or is it just a simple replacement/balance any shop can do?

Thanks

The tires have the same diameter. Nothing needs to be done, just swap and go.

nothing special just put them on, same overall diameter as 18s. Just a suggestion but you may want to rethink the forteras if you have the option to. Many people hate them, some are ok with them but generally they are not a well liked tire. I got rid of them when they only had 10k on them just couldn't take them any more, they do the jeep no justice.

Re: Changing from OEM 18" to OEM 20"

I am picking up some Overland 20's to swap out the 17's on my 2014 Laredo. So there is no re-learn procedure for the new TPMS sensors? Just install and go and they will connect automatically? Sounds too simple. On my Silverado it is a manual process of lowering tire pressure in a specific sequence each time you rotate the tires to re-learn the new positions.

They will maybe take a few seconds to recognize the new sensors. Just plug and play. Really easy.

silvermax04, you've made an interesting comment, because I purchased my Jeep one month ago and every time we had rain, I sensed that my GoodYear tires are awful, but I was not sure if my tires were the problem. My Jeep is very unstable in water and does not come even close to the stability of my previous VW Passat 4-motion with Continental tires on it. Does that sound like the problem that you are referring to? I looked up the ratings of my GoodYear tires on TireRack.com and it does not look bad at all. Where did you get your info from?

I got rid of them for a few reasons mainly , shaking at highway speeds, bad handling and noisey They wernt the best in the rain but not terrible. They are a very soft and bouncy tire and sometimes on wavey roads they get to bouncing so much i felt like they were destablizing the jeep and i did not like that. Tire rack has them 13th out of 18 in their category, not exactly good but there are others lower. How a tire performs is often dependent on the vehicle they are installed so dont let reviews always be your only data point. My info is my opinion after driving forteras for 10k miles. Some people are ok with them but i believe generally they are not a well thought of tire.
You need to buy tires how you use them there isnt one right tire for everyone. I wanted a smooth, quiet, highway cruiser that was stable, handled well and would handle the beach fine also, michelin latitude HP is great for for those requirements and 10k later i like them very much. I get minimal snow if i were in a snowier climate i would have picked the Nokian WR3 SUV which is a tire that is decent in snow which you can leave on year round, if i want more off road abilities i would have picked the nittro terra grappler. There are better tires for each of those instances if you want to change out different sets of tires throughout the year, which i dont do, but for ones you leave on year round the above are decent picks and come in the stock 20s size. Buyem how you use them as there is a different "right" tire for everyone only person you got to please is yourself.

Thank you, silvermax04. I think I will try to sell them now before they get too old

The continential pro contact is a new one in the stock 20 size and one that TR rates number one in the category and few folks on here have said they liked them well so that maybe a good choice also, really depends on how you will use them an your climate though. Just decide if the issues you have with the forteras are enough to warrant changing them because you probably wont get much for them unless they are very new. If you dont havemany miles on them some of the folks on here have done ok selling on craigs list. Mine had 10k and i didnt mess with trying to selling them and just dumped them at the nearest used tire place for around a $100 if i remember right.

I called our local Discount Tire and they said they would give me $50 for each. Since I have just a little over 1000 miles on them, I won't take that offer. Will see what people are willing to pay for them on CL. I loved the Contis on my Passat: they were quiet, not too soft, and best of all - had a very good grip in rain and snow.

Re: Changing from OEM 18" to OEM 20"

Discount Tire sells the Foretera brand new for $139 with the full warranty. The $50 probably isn't that far out of line for a takeback of what is a used tire, even with very low mileage.

That said, I ran the Forteras for over 40K miles with zero issues before moving to my current Nittos. (tread was down to 6/32 and I wasn't comfortable going into winter with that, even though we don't get much "winter" here)
