245/65R17 Tires On The Rear...

[Akuma72387]

Besides the points that people have made so far the maverick is not 90% of the time a front wheel drive it engages the rears whenever you press the pedal past a certain point, engage a mode that has more traction (in slippery, sand, mud) it detects slippage, so on and so forth. The rotating on the tires makes a big difference in my experience I am at 40k plus in my truck and still have atleast another 10-15k easily on my set so around 60k or so they will be at or past the wear bars give or take a 1000 miles.

As far as will you see an immediate difference and/or damage to the AWD probably not i havent done it to the maverick (as I said still on my original Faulken wildpeaks) but I have seen it break Subarus before and cause the diffs to overheat as the car works to try to figure out what is happening. Going wider but not taller is less of a risk so if someone has a 225/65/16 and puts on something like a 245/60/16 it works out better for the car than just adding the width as the difference is minimal 225 x .65= 146.25 and 245 x .60=147
In the OP case it's as difference of about 13mm or .5 inches doing the math but that would be on Brand new tires for both that half an inch extra is due to weight and wear from the 40k miles I would say.

Thats my experience and from what I was taught when I worked as a tire tech for Michellin but that was also 16 years ago.

So yes I have seen damage to AWD from doing it but not to Mavericks specifically

So, with the stock 225/65R17 tires at 42 psi, and the new 245/65R17 tires at 32 psi, I'm just 1/8" difference on loaded tire radius.

I'm sure most of you will say that my Maverick will break in the next 50 miles tho.

it sure drives nice.

I will not insult you, or claim the truck will break immediately.

but as a former dealer tech who knows how expensive these components are, I am...concerned

I started this thread just over 2 months ago by saying: I'm looking for anyone with real knowledge (not theoretical, or deep opinions without facts) on the reality of using different size tires between the front and back on an AWD Maverick.

As I suspected, I didn't get that kind of info... I guess humans are pretty predictable these days. Anyway, my 2022 Ecoboost XLT AWD with 4K tow still has the stock Continental 225/65R17 tires on the front (with 42, 673 miles, all of it for them on the front) and the Mastercraft Stratus AP 245/65R17 tires on the rear that I had installed 2 months ago.

I now have over 1,500 miles with this setup. I'm not here claiming that there isn't trouble heading my way, but I am here to say that I have had no problems in these 1,500+ miles. It drives normal, anti-lock braking works as it should, hard acceleration in heavy rain is just like it was when it had stock tires on all four corners. There have been no noises, smells, or hiccups. The only difference I have noted is that the my average mpg has dropped from 26.5 down to 26.2.

Obviously I'm not suggesting others operate their Maverick with mismatched tries between the front and rear, but I'm doing just fine with them.

I will say tho that it does seem that the fact that the Maverick operates predominately as a front-wheel drive vehicle (except when conditions call for AWD) and that the rear gearing is decoupled from the front when in front-wheel drive mode, there just isn't very much operational time when the slightly different tire circumferences comes into play.

I'm unlikely to engage in much conversation about all this going forward, but I felt an honest, actual update was very useful.

3,400 miles now with worn 225/65R17 tires on the front, and new 245/65R17 tires on the rear... the AWD Maverick hasn't missed a beat with the different diameter tires between front and rear. No smells, no sounds, no misbehaving. Average gas mileage has been holding at 26.2 in a mix of city and highway, with a pretty heavy foot.

I love my Maverick.

I'm looking for anyone with real knowledge (not theoretical, or deep opinions without facts) on the reality of using different size tires between the front and back on an AWD Maverick.

I have the stock 225/65R17 tires on the front, and just today had Mastercraft Stratus AP 245/65R17 tires mounted on the rear. At tiresize.com I see there's a 1" difference on diameter.

So, does anyone have any actual experience or knowledge of anyone having long term drivetrain issues when having tires 1" different in diameter between the front and the rear?

I suspect it's not likely to be an issue since the Maverick functions as front wheel drive for the vast majority of the time.

Hello,
I'm NOT AN EXPERT but have a lot of experience with buying tires and wheels. Every time I have a question I go to Discount Tire, I know the Manager very well and he has NEVER BEEN WRONG. Got me all set up on my 2020 Ford Fusion with a set of 20s and had zero problems. I would go talk to them and they can show you the exact specs on the computer. Anyway best of luck but one more thing. I do agree about not running a different size tire on the rear. Best of luck
