I'm looking to upgrade my current set of 215/55r18 firestones on my rallye. I want to go alittle wide and bigger to fill my wheel wells alittle better. Im at stock hight, 2wd, looking for a nice all-season tire. Any suggestions

I really like the triple tread design thats put out by Firestone I think. I have them on all of my cars, except my jeep ironically.

Side note: Nice to see someone else from MD, I live about 30 minutes from Bmore

Again, the Jeep Compass is not an off road unit and is designed and tuned to run a specific size tire. Going oversized can sometimes be a detriment not only for the speedometer but the overall handling of the car itself. Suspensions are built from computer data for the standard sized tires. Filling the wheel wells is not good physics.

I agree with Sky.......just be careful selecting the proper shoes for your ride.

Well, you could always put a small lift on it, but I always was a fan of the lifted vehicles, especially Jeeps...BTW Baltimore, welcome to the forum, hope you enjoy the site!

Again, lifting any vehicle can play hazards with the handling as you are going against the laws of physics. Plus, don't forget if you claim on your insurance and they inspect the vehicle and notice the lift they may object payment due to the modifications. Let's face it folks, these vehicles like the Compass are real good cars but that's all they are! They are for trips to the shopping center and commuting but not for playing combat.

Going a 1/2" wider or taller on a tire wont hurt a thing. People up tire size everyday... unless your compass is actually a Kia, upping tire size isnt really that big of a deal. If you up it a 1/2" your speedo wont be off that much, plus comps in cars now days can relearn **** like that- they can recalibrate themselves for the tire size. Or if your that much of a stickler, you could have your dealership do it. Preciate the physics lesson

 

[Cherokee]

Baltimore, you're right in that that little bit of change is not really going to make much a difference, and while the vehicle's computer may be able to accomodate the change, the TPMS system cannot, so that's the only complication I see here.

You might want to look at Nokian. They make a line of tires Snowflake winter and DOT certified to industry standard which designed for all year round use. I have them on my Grand Cherokee and my sons Explorer. Once winter get close I'll look into size compatibility etc mounted on steel rims at this time since I don't want to through out the Firestones which have tons of thread left on them.

 

[BaltimoreCompass]

Well, what size tire would you suggest for the stock 18" rim that comes on the Compass Rallye?

 

[tripplec]

You should stick to the size spec'd out on the door sticker which is what it was built for. Changing the size more than on step in profile (that the 50/55/60/70) number on your tire or width could affect performance and will change the speedo slightly.

You have to ask yourself. Why do I want to change the size. You may of course find a much better tire, thread, rubber from a different manufacture for your driving.

when I bought my compass in December it had a set of 230/50R18 snow tires on it, when I went to buy my summer tires, I bought the proper sized 215/55's. research tells me they are interchangeable with a 0.2" difference in height. The difference in driving though is unmistakable, I get 25% better gas mileage, 0 road noise, and almost double the acceleration, that can't be all drag from snow tires (other than the road noise). Maybe the bridgestone turanza el400 is just a really great tire, but I doubt it based on the fact that it was the cheapest I could find....

My Compass has P215R60/17" and I checked the OEM sticker and its says the same for tire size.

Personally I don't like too low a profile tire, 55 is certainly too low for me. I like more rubber height. If and when I need snows I am going look and see if I can install 70 series instead on new steel rims. The higher the better you don't hit curbs or rocks with more rubber between the road and rim.

I just bought a 2007 Compass a few months ago. The tires on it are 235/55/18. Everywhere I go, tire salesman tell me the original equipment for the vehicle was 215/55/18, but the dealer says the 235's could have been a dealer/factory option, although I can't find any information if the tire was originally on the vehicle. Will changing the tire to the standard size affect the driving or the vehicle?

 

[Feel for life]

Welcome to the forum.....in order to get an accurate answer we need to know more about your ride....more details that is...... model, etc !

 

[tripplec]

Every vehicle comes with the OEM build info for specified tires. There size and tire pressure. Check around the doors/door jams. I don't have mine here but it shouldn't take more than 30 sec to locate it. There you'll see what Jeep put on you vehicle day one!! Any changes other than that and you're on you own.

 

[smokey01]

It's on the back side of the drivers side door jam.

Thanks for the welcome.

The vehicle is a 2007 Jeep Compass Limited. As previously stated, the tires on their now (on the Jeep when I bought it) are 235/55/18. The door does say the original tires were 215/55/18.

Seems you have your answer now. Up to you which size you used next as to whether the dealer changed it you'd have to check with them or customer service who has or should have access to the build sheet on you VIN. Narrow tires are better on the snow since wider tires float more with less pressure on the surface.

I bought my 07 limited with 235/50 18 snow tires on it, and in the spring got a set of the recommended 215/55 18's I noticed an improvement in gas mileage right away going to the factory recommended tires, but I was also going from snow tires to touring tires...bottom line is the difference between the 2 tires is about a half an inch, and they both fit on the rims so the car doesn't know the difference anyway! when I was shopping for summer tires, I found the 215/55's to be a more common size (cheaper) than the 235/50's and as was mentioned above, I really only need the narrower tire in the winter anyway
