Hey folks,

New to the forum here with a newbie question: I just purchased a 2003 Chevy Tracker 4wd, and I am running Bf Goodrich All terrain tires on it. The tires size is 215/75/R15 but the tire you are suppose to use is listed on the door as 205/75/R15.

Do you think there is any significant issue keeping these tires on? I have been using them on logging roads here in BC, and they have been excellent so far.

Thanks in advance for any advice!

your fine...as long there is no rubbing issues.

For ABS, stability, traction control, abs based tpm systems and 4wd operation is important that all the tires are the same circumference...ideally size, brand, within 3/16" treadwear.

Thanks for the help ya'll! Much appreciated.

Just remember that the speedometer may not be showing the actual speed due to different tire sizes from what may have been originally installed. Use a GPS your 'true' speed to your 'indicated' speed. Otherwise, no issues. As mentioned, on any 4WD the key thing is to have all four tires the same size.

I have a 2004 Tracker ZR2 AND a 1999 Tracker 2 door w/1.6L engine. The recommended tire size is 215/75-15 for the ZR2, which is what I am running on it without any issues. The recommended tire size for the 1999 2 door is 205/75-15. But I run 235/75-15 tires on this one. However, the 1999 also has a three inch lift on it. The only issue with the 1999 Tracker is when I turn the steering wheel to full travel, the tires do barely touch the vehicle frame. I rarely if ever need full travel on the steering so it’s not an issue for me.
I wouldn’t be surprised if you could get away with 225/75-15 tires on your 2003 Tracker with a 2.5L engine.
Enjoy and have fun.

The actual difference between a 215/75 and a 225 /75 is 10 mm in width - or .4" (that may vary very slightly depending on the tire manufacturer). The difference in height is .75 meaning that the height is .75 times as high as the width (tire profile as a ratio: 215/75 means that the tire width is 215 mm and the height is .75 times as high as the width).

So, as pointed out, the key thing to look out for is what happens on steering full lock - including when the suspension is fully compressed as it would be going over a bump. The clearance to suspension or body components might be minimal. Other than that, you are good to go!!

Just for accuracy, tire tread depth is measured in 32nds of an inch - there are 4-6 moulded around the tire at the bottom of the tread that go from side to side and sit 2/32" above the flat, worn out stage. That allows for a quick look at the tire tread and, if you see a 1" wide patch of smooth flat rubber across the tire tread, it means that the tire has worn down to a tread depth of 2/32" and needs to be replaced.

just noticed....meant to say.....tire treadwear for 4wd operation should be within 3/32" not 3/16"
