I havea 98 ford expedition and i need stock tires and wheels for winter, what is all the tire sizes that will fit and rims

For tyre sizes do you understand what all numbers mean? I've described them below just in case you don't.
If your changing tyre width you need to adjust the side wall size. Changing the rim size will also need the same adjustment. Generally a narrower tyre will need a taller side wall to keep the wheel size correct. The wrong tyre size will affect your speedo reading and affect the handling and grip of the vehicle.
To drop to a 16 inch rim the 225/55R17 would have to be either a 255/50R16 or a 215/60R16.
To go up in rim size the 195/70R16 would have to be a 255/45R17 or a 285/40R17.

Using the 225/55R17 - 6.5J x17 as an example.
Tyre size.
- 225 is the width of the tread on the tyre in mm.
- /55 is the side wall measurement as a percentage.
- R is the tyre is a 'Radial' construction type.
- 17 is the rim diameter in inches.
Rim details.
- 6.5 is the width of the rim between the points where the tyre attaches to the rim.
- J is the code for the shape of the seal edge.
- 17 is the rim diameter in inches.

When changing rim sizes, you need to manage the "height" of the tire to compensate. Usually folks are shifting to larger rims so to keep the circumference the same, a lower profile tire is used. If you are going from 19s to 17s, you will need a much "taller" tire. I believe Tire Rack has a calculator that can help with tire selection. Tire Tech Information Tire Size Conversion Chart

Here's what you need to do. You need to get the tire size off of the tire on your vehicle. Lets say its P205/75R14 or something like that. Go to this link, type that size into the tire on the left, then you can change the tire on the right to whatever size you. You will be amazed what will fit on that vehicle. I wouldnt go over 20" rims if i were you. 22's will leave you very little tire and a very bad ride.

Here's some info on your bolt pattern and wheel offset.

Any question, comment back. If you are looking for 20" rims, 255/30/20 is a common tire that you can find reasonably cheap and lines up perfectly with most vehicles.

that depends on if your doing a stock upgrade or if your have ing a lift kit also installed, depending on the kit itself, would open or limit the tire and or rim size

Barely but they do fit. If you went to 275's then you would be having other problems

you need to understand how tire measurements work.

P245 = the width (245mm)
75 = Ratio of the Width or 75% of the Width
16 - Tire Rim Size

so the height is the issue, the wider the tires, you start to have another problem.

Width for turning
Height for Bottoming out

Hello Projocs03,

Tires are typically measured tire width (sidewall)/tire ride height/wheel size. The differences of the two tire sizes you published are .4 of an inch difference in width/sidewall. And about .55 in over all diameter which would impact you revs per rotation. Depending on your wheel size.

Attached is a comparison of the two given the variable of 17" rim.

I added the above link so you can research further or change any variables you need to know. However, the most important thing to understand is the impact of your speedometer. Different sizes will have different impacts. For example going to a bigger tire will show a slower speed on your spedo that your traveling.

Good luck

I believe it will fit. If you go to DiscountTires.com you can use their site for alternate tire sizes. Especially handy is the feature which shows you the Speedometer error for different size tires. The site will also show you recommended and popular substitute tire and wheel sizes.

The 1999 model had a 265/65/17 as an alternative. You may want to ask the Tire store you intend to use if they can reconfigure your Speedo to be accurate. Some of the Fords can be done electrically without changing Speedo gears.

I did something similar by going from a "60" series to a "65" series in the same width. On my Grand Marquis, I gained 5% mileage improvement, but have to watch Speedo until I get it reconfigured. I hope this helps to answer your questions.

The best way to find out is the door sticker on the driver side door.

There are two possibles sizes for that truck. The 16" rim or 17" rim.
The tire size is P255/70R16 or P265/70R17.

The factory sticker on the door jam on the driver side will tell you what it came out of the factory with.

Yes the 235/75R-15 tire will fit on your rims, they were the stock size tire for the Bravada.

BFGoodrich makes a REALLY nice tire for the beetle that fits on the stock alloy rims. If you have the 16 inch rims you'll probably need to be running 205/55/r16's. I can't remember the exact name, but they make some decent winter treads. Either way, the beetle isn't the greatest in the snow so I fixed my problem in a different manner.

I got 4 rims off a beetle from the junk yard and put 215/55/r16's on them. They are a winter tread from Hercules Tire. They really helped my 01 beetle in the snow. It may have been expensive, but they keep wear and tear of winter driving off of my clutch. Also, it saves some of the tread on my Yokohama tires :)
