US Offroad rigs � tire & lift helper

Offroad tools hub for Jeep, Toyota & Ford

Q: Which calculator should I start with for my offroad build?

Start with the tire size calculator to choose a realistic tire size for your Jeep, Toyota or Ford. Then use the gear ratio helper to see if you should regear, followed by the payload calculator and fuel cost calculator to understand weight and running costs.

Simple calculators for real-world offroad builds. Start with tire size and lift, then check gear ratios, payload and fuel cost before spending money on parts.

Available tools on OffroadMe:

Tire Size Helper � multi-vehicle suggestions (JK, JL, 4Runner, Tacoma, F-150) with simple visuals.
Gear Ratio Helper � rough regear ideas when moving to 33�37" tires.
Payload Estimate � approximate payload usage with passengers, armor and overland gear.
Fuel Cost Calculator � estimate yearly fuel cost when MPG drops after a lift and bigger tires.

Which calculator should I start with for my offroad build?

Start with the tire size calculator to pick a realistic tire size for your Jeep, Toyota or Ford. Then use the gear ratio helper to see if you should regear. After that, check payload and fuel cost to understand weight and running costs.

Are these tools only for Jeep Wrangler, 4Runner, Tacoma and F-150?

No. The calculators are focused on common US offroad rigs, but you can use them with any SUV or truck as long as you know your tire size, gear ratio, payload rating and approximate MPG.

Are these offroad calculators 100% accurate?

No. All tools on OffroadMe are simplified estimates to help you plan your build. Real-world fitment, axle strength, exact gear ratios and MPG depend on many details such as wheel offset, driving style, engine and transmission.

Can I use OffroadMe tools for overlanding and camping builds?

Yes. The payload calculator and fuel cost calculator are especially useful for overland builds with rooftop tents, drawers, fridges and recovery gear. Combined with the tire size and gear ratio tools they help you design a balanced, safe setup.
