Colorado Newbie Tire and Oil Questions

Tires:

I am torn between keeping the stock tires for improved comfort and fuel economy, or replacing stock tires with stock size BFG KO2's, or going up one size to 275/70/18 KO2's since that would look awesome with stock suspension. But I can't decide! Is the ride that much worse with load rated E tires? Talk me into keeping stock tires....or at least stock size tires....because I really want bigger and I don't always do the sensible thing when it comes to trucks! Also, I understand that MPG takes a hit with the bigger tires. I'm also adding an ARE topper this week...which will be an additional hit...so talk some sense into me before I go around driving a 10 mpg truck!

Oil:

Should I do a break in oil change....and if so how at what mileage? Looks like I have 2 years of free Toyota oil changes. Does Toyota use synthetic oil? Should I skip the freebies and go to mobil 1 now or wait until after the 2 years? It looks like they will do the oil changes every 10,000 miles.

Thanks for all the great advice on here so far....have already done a frew mods: FRAC harness/camera, TRD Airflow accelerator, blacked out badges, TRD center caps, ultra guage, Tuff Skins.

 

Good to know that Toyota already uses Mobil 1. On my Wifes 4Runner the dealer used Penznoil...which pissed me off! Having never ridden with a 10 ply tire....just how much different is it? Will my fillings rattle? Is there such a thing as an off road ish type tire in Tundra size that is not 10 ply?

Welcome from Burlington! Where are ya located in this beautiful state?

I went up in size when I lifted mine, but I don’t think my LT tires ride worse than the P-rated ones that came on the truck. Maybe I’m just so used to running LT tires on my work truck that I don’t detect a difference. But the LT’s do feel more “stable” to me, so that’s why I like them more.

LT 275/70R18 is a good size on a stock Tundra, go for it! I only took a 3-4 mpg hit running skinny 35’s, so I have a hard time seeing ya losing much for smiles per gallon.

 

Im in Castle Rock CO. I only have 230 miles on the truck so far....all in town driving. And I'm averaging 11 mpg. Winter gas right now...so not as good anyway. But I'm expecting a 1mpg hit with my ARE topper that gets installed this week. That is why I'm having a hard time deciding what to do. Is there any issues if I do go up 1 size and then have a spare tire that is 1" smaller?

 

Damn that’s low on stock tires, do you put pedal to the floor all the time or are you generally driving pretty conservative? In the end though, it’s a 6k lb truck, not a Prius. It’s always ideal to have a matching spare, but I have a hard time seeing a 1” difference being a huge deal.

 

Moderation is only applies to drinking, get the tires!

 

Break in is your biggest issue right now. After the break in period you will end up at about 14 I am guessing. I drive 90% hwy so it is hard for me to relate. It is more weight than size that will impact you MPGs. Tread design will make a little difference but how many have compared different treads in the same size tire. As far as size it is width that will create more rolling resistance. When I have gone up in diameter I usually go down a little in width to offset the extra weight somewhat. The best off road tire for mud and puncture resistance does not always make the best snow tire. For the off roading I do I like a open tread that will kick the mud out. Snow on snow provides more traction than rubber on snow so when you see a true snow tire it will have more of a closed tread than a mud tire. Not saying that some ATs and MTs are not good in the snow just you can do better. I would think your concern is more snow than mud. I have also heard that a smaller is width is better in the snow

 

Where are you in CO? I have a tire guy in Lone Tree at discount FYI. Thinking about doing the same thing. Probably going to add a RTT for next season so I don’t want to level it right now and get the bro lean.

 

Welcome. Another option is 285/65/18 for stock suspension. Get winter rated all terrians. You will like the look difference and enjoy the performance difference.

I have a smaller spare right now too, just make sure the spare goes on the front. You want matching size tires on the rear drive axle. On the front and not in 4x4 and the smaller spare will be fine.

 

No warm up.....I’ve never warmed up a vehicle really. But my trips have all been 10 minutes ish. It’s not my daily driver. I’m sure the mpg will improve once I start taking it on some longer trips.

 

I’m in Castle Rock so lone Tree is very close. Please send me your tire guy and I’ll give them a call. The discount tire in Castle Rock hasn’t been that great for me in the past.
