ok, simple... I hope. has anyone done a swap to the 19.5" rims and tires and still gotten the same MPG and ride quality?
just looking for longer tire life is the goal for me.
thanks for any and all input

i had them on my truck for a while. They rode about like stock, but were impressive with the trailer weight on them no squirm at all. Got rid of them because of the toms sensors would not transmit through the tires with steel belted treads and sidewalls. it started to drive me nuts with that thing chiming all the time.

 

MPG stay about the same, accounting for difference in diameter?
longevity of the tread? miles?
thanks for the info

can't tell you much about mileage since i only use my truck for pulling my toy hauler never gets driven otherwise, so its always about 11 mpg. I only had them on for about 5k miles and they looked good as new. If you can figure out the tpms issue they are great.

 

Hey Fert, what model truck do you have, F450 or 550?

 

2016 F 250 4X4
my concern is from when I had a 2008 F 350 that went thru tires faster than I would have expected
thanks for the help

Why wouldn't you go with a 20" wheel and a commercial grade tire instead? 19.5 rims are very tire specific and dont leave much option for upgrade.

 

Just be careful as it is hard to find a commercial grade tire that has a high, highway speed rating. I found some 20" goodyear tires that would fit stock rims. Load range H, they weigh 155 lbs (compared to 75) and are speed rated to a lightning fast 68 mph... I don't know about you, but I do find myself running empty faster than 68, especially when the speed limit is 70 mph or greater.

 

ok when I drove OTR the tires be it 22 low pro or 24 talls had almost 1" of tread depth, look at a tire for cars or light trucks... its about 1/2"


I got 100K miles on steer tires and 200K+ to 300k miles on drives depending on how good i was to them and how heavy I was running.


so now take a true truck tire and install it on a 8k lbs truck.... last tires you ever buy unless they dry rot off the rims


that is how I am looking at it. but I am not as deep of pockets as some and deeper than others... that is why I was asking if someone has actually done anything like this? I dont want to replace spindles , just bolt on rims that fit and drive with no loss of MPG basically. It is just a daily driver for me, when I haul it is rare but usually a load so to speak. so 19.5 or 20 or 22" rims it dont matter to me.
thanks for any and all input

I'm watching this thread. I always wanted to do what you are doing fert. I just haven't found the right tire and rim combo. The speed rating or the cost always get me.

 

If the speed rating can last the open west texas desert at 112 MPH during a sunday morning drive @ 40 tons.... then the 8k lbs truck will never hurt those tires


Fert

 

Which tires? What make and model?

 

at the time the truck was on 24" rims, and I believe it was firestone tires. as to the model?? heck that was 12+ years ago

Not to be a smart a$$... But for all we know the tires were rated for those speeds...

Whether it is 'needed' or not, I tend to follow the weight and speed ratings of the components on my vehicles. My reasoning is that if you get into a accident or a tire shreds and you were going faster than the speed rating of the tire -- you get a lot of the blame for the accident. The chances of some LEO pulling over a F250/f350 with commercial tires and checking the speed ratings has got to be close to winning powerball, but get into a fatal accident and those chances go way up... Not that I Plan on getting into an accident at all - as no one ever does.

Like I said, this is something I wanted to do as well -- and I keep researching it too. I hope we both find the answers we are looking for!

 

after looking at Goodyear commercial tires, they are all rated at 75 mph unless you get into a mining tire that is rated at 68 mph but has a tread depth far greater than the others. but all of the tires i was looking at for 11R20, 225/70R19.5, 245/70R19.5 or 8R19.5 has a weight rating of 3500 lbs to 7390 lbs. the speed rating is an issue of the weight that the tires can carry (max) and still not blow. if the tires are running way less weight then I would feel very comfortable running them past the speed rating. heck be serious, you going down the highway at 85 mph all the time? maybe if you live in west Tx with high speed limits, but then you are just blowing fuel out the back, loaded or empty.


My idea is to not have to buy tires every 50-70K miles, thats all and not lose alot in mpg.
