Will I have regrets with 295/70r18s

[AlexC2350]

I just scheduled new tires to be put on tomorrow. After much debate I went with my original plan of 295/70/18 coopers at3 xlt on stock steelies.

I currently have the same tire in 275/70/18 that I had put on my previous 18 2500 6.4 with 3.73s. I lost about a mpg putting those tires on that truck. When I traded the truck I had the tires swapped over as they were still very new, so I never did get to see the mpgs of the Firestone’s on my 2020 2500 6.4 with 4.10s.

I specifically went with 4.10s because I wanted to put a taller tire on and not sacrifice much performance. There is only 4 pounds difference between the 295’s and the 275’s I have on so I don’t think that will be much of a factor as the 1” increase in height and width.

Am I dreaming that I could see an increase in highway mpg with the reduced gear ratio as a result? Or that I won’t see much if any decrease in overall mpg. I drive this truck daily, many hundreds of miles a week. I get money for fuel and the truck from my company but I still don’t want to take too much of a hit.

a 295/70-18 is a nice size tire altho if I were given a choice and was set on 18's I would go 285/75-18. a little taller and narrower. I have a 2020 with 4.10's and see zero difference mpg wise between 35/12.5-17 and 285/70-17 altho in my case there is 20lbs difference in tire weight. I run both sets as I have both mounted on wheels and switch back and forth whenever I feel like it. I notice a difference in peppiness with the smaller tires but not in mpg. I calibrate my speedometer so it is accurate each time i switch.

That’s good to hear on the performance front. I should have said that the 295’s were my second choice after the 285/75’s. There is a big wait on the coopers in that size and they’re quite a bit more expensive, so my hand was forced. I thought about another brand in that size but they’re all much heavier and even more expensive.

What are you using to recalibrate your speedometer?

I got my tires on today and I’m pretty happy with them. I’ve had a few sets of these tires now, never this size and love them. I miss my raised white letters but I think it’s a good trade off. No performance negatives that I could tell so that’s great. I’m going to get AEV procal snap also.

I'm running the same tire just a tad smaller than you at 285/75/17 and they're a good mix of style and function- I didn't want to go big while towing 11k. I'm also running 3.73 gears because that's what was available when I bought- it had to come from MA to get the few options I do have. Good to see another from New Hampsha on here

Yup born and raised in the free state! I agree this tire size seems to be good compromise. At the end of the day it’s a work truck it needs to be functional but I like a bit of style. I shot down to Connecticut to get my truck because there wasn’t much here, and the 4.10s with the v plow already on it.

I wouldn’t normally post pics of an unwashed truck but It’s been too rainy and I’ve been too busy.

Wow, so rude to post pics of an unwashed truck. The nerve….
Looks good!

Thank you. Those are boost autoparts, gm style mirrors.

Nice Mirrors. Had them on my 18 2500. My tires were 295-70-18.
