Hey fellas, Im new to getting offroad and what my vehicle will need. I have a 99 4runner limited 4x4. Stock rims that i think are 16x7. Im looking for a new set a tires. Im not sure what brand or size would be good though.

I ride around the city a lot, but im looking for a set of tires that will help on weekend trips to the beach. I have stock suspension on my 4runner. I want a more aggressive look but hopefully will work with stock rims and suspension. Any help would be appreciated.

 

look at a 265/75r16 BFGoodrich All-Terrain. If you want the beefier look check out their Mud Terrains. A bit on the pricey side but worth every penny

 

You could also check out the Nitto Terra Grapplers in 265/75/16. You can find pretty good prices at Discount Tires' eBay store.

 

Also check out the Toyo Open Country AT's. http://www.toyo.com/docs/tires/tires...?&category=lgt Like others have suggested go with the 265/75/16's

 

Awesome thanks for the quick replies guys.

 

Just a warning, you will lose about 2mpg going with 265/75's. That's what I experienced, anyway (went from 20mpg avg to 17-18mpg). I'd also throw out the good ol' REVO's. They make them in the stock size of 265/70's or 265/75's.

 

He did say just weekend trips to the beach.


Buy a tire that has solid pavement manners instead of leaning toward a tire that has so-so on-road performance and costs a lot like a BFG or a mud tire which isn't that great for pavement period.

I'm partial to the Nittos cause their everyday driving performance put's a BFGs to shame and cost quite a bit less but if you really don't off road any AT tire might be a bit much. Revos are a good choice since they do have a mileage warranty and can easily handle the sand on the beach.

My truck on stock size tires only really saw 17-18mpg with suburban driving and once I went bigger and a bit heavier D load rated Nitto it dropped to under 17 mostly but I think I only saw maybe a 1mpg drop consistent.

 

When calculating your MPG, don't forget to account for the change in the odometer. A larger tire turns fewer times per mile of road, and your odometer will show fewer miles than actually driven.

If you go up 10% in tire size, add 10% to your miles driven, before calculating MPG. Or add 10% to your final MPG calculations. It works either way.

 

265/75s I think come out to 3%.

 

At 3% tire size change, and 18 MPG, you will need to add 0.5 MPG back into your final calculation, to account for the incorrect odometer reading.

So; if you were getting 17-18 MPG with the smaller tire, and now it is 17 MPG with a 3% larger tire, add back in the 0.5 MPG and you are at 17.5 MPG. Your actual fuel economy has not changed.

You were probably just below the optimum gear ratio for fuel economy, before the tire change, and now you are just above the optimum gear ratio.

 

If I get 250 a tank with my larger tires I add about 8 more miles so .05 is pretty close.

 

Really? Mine came stock with 265's and I got 21-22 I added lift and 295 Nitto terra's and got 17mpg when I switch to my other set 285 Cooper STT's I get oh 17 mpg. Kinda wish I still had the 265 for the fuel economy standpoint.

Don't try calculating your MPG, by how many miles you get to a tank of gas. Unless you are sputtering on fumes, every time you get to the gas station, you have no consistant quantiy of fuel per fill-up. The way to do it, is to write your odometer reading, and gallons to fill up, each time you get gas. It takes an extra 60 seconds. Don't be lazy people. If you don't do this, you don't have good information. It is like "seat of the pants" horsepower testing. IT IS BS.

So; what I am saying for those that increase their tire size, don't forget to account for the odometer corrections. If you forget to do this, you may think your MPG is lower than it actually is.

I put larger tires on my rig. I went from 265/65R17 to 275/70R17. This was an increase of 5.5% in tire size. After accounting for the odometer corrections, I did drop 1 MPG. (This measurement was figured over 3 months, and compared to the same three months from the year before. This accounts for the seasonal change in fuel mixtures).

I had more than 1 change to the vehicle. I did a lift and tires at the same time. The wider tires have more rolling resistance, the taller tire has more torque resistance, the taller tire messes up the odometer, the 3" lift increases aerodynamic drag.

So; with an ACTUAL 1 MPG loss, we are doing great.

 

Aaron,
What size tires were/are you running? 265 and 295 are tire widths, in millimeters. How tall were/are they? With the rest of the tire size information, we could figure out how tall they are.

From that, we could figure out an odometer correction, and then you could calculate an mpg reading that is meaningful.

Back to the topic:

Tikal769,
You had the original question about what size and type of tire to put on your 1999 4Runner. The factory size is 265/70R16 (31x10.50R16). Your 1999 4Runner is the tallest of the factory suspensions, and has the most room for larger tires.

The 265/75R16 is 1" taller (32X10.50R16), and would fit easily.
The 285/75R16 is over 2" taller, (33x11.50R16). It might fit. Search the site for tallest fit with minimal trimming.

As for tread patterns - The Goodyear Silent Armor LT, is great on the street, and tough enough for rocks and dirt roads; and it won't dig down in the sand. They have strong sidewalls and you can air them down for better traction. It looks much more agressive than street tire; but not as agressive as mud tires.

 

Yeah, it was disappointing. Most 4x4 4Runners come stock with 265/70/16's, but you can go up a size to 265/75/16's without a problem. It is an inch taller than stock, so that's where the extra MPG loss comes from, along with the extra weight of the A/T tire compared to the crappy A/S Dunlops.

I calculated my MPG's using the same method as photog and kept strict records. I was averaging 20-21MPG, then suddenly dropped to 18MPG after I got the bigger tires. I did calibrate for the increase in size. I should also note that my 98 4Runner was supercharged.

Also would like to reiterate:
