I know, this has been asked a thousand times, in the past I did a search on this forum (I can no longer find the search feature) and I even searched on some FaceBook groups too.

My Truck:
2020 F150 Lariat / SCREW / FX4
Stock 275/55/20 - 32" tire
Stock 3.55 gears
100% stock level and do not plant to put a lift on it

I am having a hard time deciding on the following tire sizes and what tires to go with. My driving consists of easily 90% country roads / hwy of speeds 65+ mph and the rest is city driving; under 55 mph. I can re-calibrate my speedo using my SCTX4 tuner so I am not worried about that. Gas mileage isn't too concerning. in the spring/summer I average (hand calc) 19.4 mpg - 19.7 mpg. Fall/winter my gas mileage drops to 16-17 mpg. I am on a 93 octane tune.

I want to minimize some body roll so I am not sure what load range tire to go with, but I also want to maintain a smooth, quiet ride.

Tire sizes I am thinking of going with:
275/60/20 - 33"
275/65/20 - 34"
285/60/20 - 33.5"

Tires I've run with before on my Jeep:
GoodYear Wrangler Duratracs
BFG AT KO2

I had zero issues running those 2 above mentioned tires. I got plenty of tread life out of them as the key was proper inflation and I rotated every 5k miles too. Now, seeing as I am strictly pavement and on the highway, i do live in SE Wisconsin where we do see our fair share of snow.

I was thinking maybe running the Continentals tires or even the Michelin tires.

What are your thoughts? Does Continental or Michelin make a semi aggressive tire? What is the biggest tire on 100% stock suspension can I run without rubbing lock to lock?

Please help me decide. Thanks

EDIT: Here is the list of tires I am thinking of getting. Since I am staying 100% STOCK suspension, looks like 275/60/20 is as big as I can go.

I wonder if the 275/60/20 will rub on my Husky mud flaps.....

BFG TA KO2
Falken Wildpeak AT4
Continental Terrain Contact A/T
Continental Terrain Contact H/T
Falken Wildpeak H/T HT02
Michelin Defender LTX M/S2
Michelin LTX A/T2

 

If you level, the BFG 275/65/20 would look best IMHO

 

275/65/20 will fit without any lift or level if you use factory wheels

 

Curiosity raised....
what are you running now?
Are you getting 19+mpg at highway speeds w 93 octane?
My buddies with aggressive off road tires say that mpgs drop.
tread patterns of the same tire can change when sizes (or loads) dramatically change. So, if I understand you, the 'jeep' patterns may be different than the F150 patterns. check in person if this is important to you.
You may know this: the lower sidewall (60) will provide tighter handling than the higher sidewall (65) - other items constant.
Do you have room to store off-season winter only tires? This would allow you a more street friendly 3 season tire. You may have other factors more important. NP.
Have you posted this ? in 'Wheels and Tires' section?

 

I think I may be leaning towards this size. I will be using my factory, OEM wheels

 

There have been a few people that fit 275/65/20 (certain brands) without rubbing and I have seen quite a few get a little rub especially when turning an hitting bumps.

On a stock truck and stock wheels, i think the 275/60 looks the best.

Im not sure i understand your usage...seems to imply 90% country roads but at hwy speeds? If you can drive 65 on a country road, we might have different definitions of country roads. I have to find a better All Terrain tire for wet, dirt, gravel, dry pavement, and snow than the Falken Wildpeak. If you arent doing an AT, i would get Continental or Michelan HT.

 

For some reason, I cannot post in the "Wheels and Tires" section...

 

you’ll get more responses here anyways

 

I'd love a 275/65 for the bigger sidewall which will help body roll. I jsut do not want it to rub at all..... I am torn between 275/60, 275/65 and 285/60

Yes, country roads, our speed limit is 55mph. I go 60-65mph which is hwy speed. Our minimum hwy speed is anywhere between 55-60 mph and our max is 70 mph. So, yes, hwy speed on country roads.

I believe Continental or Michelin make a semi aggressive tire. I need to see if I can find it. I know the Michelin Defender is a very popular tire.

 

So, these are asphalt roads? If so, why dont you go for a street tire with more rubber and better grip? I do understand if looks are part of the equation......
