speaking of tires...

[John in Santa Cruz]

I took a pic of my tire for no particular reason the other day, and upon studying it at my desktop, I noted a couple anomalies...



1) their is a radial 'bump' at the 2nd R in MASTERTRACK

2) there's a circumferential 'bump' just about midway trhough the tire size.


are these things I should be concerned with? I was hoping to get another year out of these, and get new tires towards the end of next year, in preparation for a 3 month Mexican trip in early 2024.

Remember 7th Heaven? He had to have a wheel well repaired due to a blowout. Why take a chance?

My 2 year old(exactly) Goodyear Endurance tires are at about 4/32. I could run them another trip of 5K miles, however am getting a new set next week. Last set was $460 OTD; will report on what they quote next week.

Right now the GY Endurance tires list for $142 (USD) each plus installation, balancing and disposal fees. I was just quoted $750 for five. Carlysle Radiial Trails (8ply) would be $70 less. I'll be interested to hear of other pricing.

My Carlysle Sport tires look like new, with less than 10K miles, but since they are six years old it is time to swap them out.

In a lot of areas there’s a “Used tire guy” usually operating out of an old filling station in my experience. If your old tires still look pretty good and you have such an operation close by, instead of paying for disposal, you might check, before you buy the tires, if the used tire place has an interest in trailer tires. That’s what I did with my last bunch and I got a little money for them. Just a thought.

John, do yourself a favor and get yourself some real tires. Ditch those "ST's" and buy some light truck tires. You'll never regret it.

At the trailer max load, those tires have 1000 lbs each on them... That's pretty light. My "LT" has like 2200 lbs on each wheel if it's evenly distributed (it's not)

I don't see it... what am I missing?

Thats easy for you to say, you have an Oliver with 16 inch rims, and came equipped with LT tires.

John, and I, and tens of thousands of others have smaller rims. I have the same size John has, 225/75R15. There are NO true Light Truck tires made in 13/14/15 inch rim sizes, you have to step up to 16 inch or better and you can clearly see that he has no room for anything larger.

A genuine light truck tire will have LT preceding the size, just as a trailer tire has ST in front of the size.

I have Goodyear Endurance ST225/75R15 tires. They are rated at 2830 lbs each. That is 11,320 lbs total capacity. They are mounted on Sendel rims rated at 3200 lbs each (12,800 lb) and installed on axles rated at 3500 lbs each (7,000 lb) for a trailer with a gross weight of 7000 lbs. I typically run about 6000 lbs and 800 of that is tongue weight.

actually, mine are 205/75R15 not 225... This is a very common trailer size. but yeah, pretty sure no LT in those sizes. in reality, even range "C" tires, as specified by Escape, are overkill. figure 4000 lbs on 4 tires, thats 1000 lbs each. I run them at 50 PSI as Escape specified even tho my current tires are 'D" and max 65 PSI..

Hey Scooby Do! Yeah, you probably have 16" wheels and can get Michelin tires. In 15" there really ain't much I'd be interested in.

Getting a new set of Goodyear Endurance when I get back from Sierra. $500 total for 205/75 R15. Works 4 me!

John, according to a retired tire engineer's website here https://www.rvtiresafety.net/, the radial tire bump at the second R is not of concern. However, the circumferential bump at the tire size would worry me, it looks like the tire was 'curbed' and the plies are starting to separate.

Thanks for posting this; good education.
