Load Ranges, Service Descriptions, and Upsizing.
I have addressed service descriptions before, but I want to combine this with load ranges today to dispel some of the misconceptions about these items.
First, what is a load range? Simply put the Load Range is synonymous with ply rating. Long ago, tires would have several plies of belting material, for example 6 belting plies gave us a 6 ply tire or C load range. Simple. Not so much anymore. You will see six plies in a tire, but what about a load range E or 10 ply tire? This tire might have actually had 10 plies back in the day of bias construction, but not anymore. Tires are made with less material these days and don’t require the additional belting material. Thus, a load range E 10 ply rated tire is just that rated at 10 plies. See what Toyo has to say in the following info-graphic.
Second, What is the service description? The service description is made of two components, the speed rating and the load index. The speed rating tells us how fast we can go on the tire and the load index tells us how much weight the tire carries. The service description looks like this – 123R. A tire with this description will have a max load per tire of 3417 lbs and a top speed of 106 MPH. When replacing tires, you can increase both*, but it’s recommended not to downgrade the speed rating or the load index. Otherwise, you lower the top speed the vehicle with a lower speed rating, and when you downgrade the load index, you take capacity away from the vehicle.
A rule of thumb in the industry has always been, if its bigger and has the same load range it will carry more weight and will work. Let’s take a look at how easy it is to unwittingly downgrade the load capacity of the truck based on this outdated thinking.
Example Vehicle: 2012 Ford F-250 Super Duty with 20 inch wheels
Original Tire: LT275/65R20 E 126S
Height: 34 inches tall
Replacement Tire: 35X12.50R20 E 121Q Open Country M/T
Height: 35 inches tall
So, why would I say this is tricky? Because when a person like myself sees the two sizes and load ranges, we would automatically think the 35 will work because it’s bigger. However, we see from examining the Load Ranges and Service Descriptions that this not the case.
Think it’s not a big deal and its close enough? Toyo, in an example like this, would not cover the tire for warranty since it has been miss-applied. So make sure you’re looking at not just the Load Range but also the Service Description when upsizing your vehicle and choose the right tire.
*Increasing the load index or ply rating of a tire does not increase the load capacity of the vehicle. It only increases the load capacity of the tire.
On the road again, then….UGH! Calamity strikes. Or, just a minor hiccup.
Make sure not to doom your road trip and be prepared in case of emergency. This seems like such a no brainer when so far from home, but does your vehicle have an Emergency Roadside Kit? And really, who says you have to be far from home? You really just need to have an issue that doesn’t fit into one’s normal routine. Although these tips come from NHTSA’s Summer Driving Tips 2016, they apply to every day and every season in your vehicle.
They suggest keeping an Emergency Roadside Kit. The first item is something you probably carry every day anyway and that is a cell phone. But do you have the second in your vehicle? The charger for your cell?
Here is their complete list:
- Cell phone and car charger.
- First Aid Kit
- Flares and a white flag
- Jumper Cables
- Tire pressure gauge
- Jack(and ground mat) for changing a tire.
- Work Gloves and a change of clothes
- Basic Repair tools and some duct tape (for temporarily repairing a hose leak!)
- Water and paper towels for cleaning up. (Being a new dad, I’d put wipes in there too.)
- Nonperishable food, drinking water, and medicines
- Extra windshield washer fluid
- Maps – what if your Mobile Phone ran out of power or no service, no more Google maps.
- Emergency blankets, towels, and coats

Tirecrawler wants your family to be safe. When putting kids in car seats, you should keep them rear facing as long as possible. The State of California is making this mandatory for children under the age of 2 as of January 1, 2017. Please read this informative flyer from the state outlining important child seat issues.

Give your tire the Presidential Treatment.
Have you ever heard someone say you can check your tires with a penny? Well, it may not be 6 sigma accuracy (99.99966% accurate), but it’s a close enough approximation for every day driving. Let’s see how it works.
The depth gauge is an important tool for us in the automotive profession. The tool is useful to tell us the amount of tread remaining on a tire. When a tire is down to the wear indicators it is at 2/32nd inch tread and should be removed from the vehicle.
“That’s great”, you say. “I’ll Just look out to see when the tread intersects the wear indicators then I’ll know when my tire’s life is over.” Not really, and that’s where you need the gauge. There are several wear indicators spread over a tire’s surface, but they’re not everywhere. If a tire is worn unevenly or choppy the area where there’s an indicator may have a lot of tread and the tire could be down to 2/32nd inches elsewhere.
This is where President Lincoln come in. I’m blabbing on about gauges you don’t own, but you do. In fact, there are probably a few gauges under the driver’s seat.
The depth gauge to the right is measuring the gap to Mr. Lincoln’s head, about 2/32nd, a little closer to 3, but that’s splitting hairs. The image below shows President Lincoln in action showing us a tire in need of replacement. I used this tire on purpose to demonstrate a point. It doesn’t matter where the tire is below 2/32nd inch tread, just that it is. So, When you perform this test, make sure to do it in a few spots.
So get out there and check your vehicle out and give your tires the Presidential Treatment.
