Results for "DOT code"

Pulled into three different tire shops asking about RV tire replacement and got three completely different answers about when tires actually need replacing. The unit has six tires with 2018 DOT date codes, making them 7 years old as of 2025. Mileage is approximately 28,000 miles, and visual inspection shows good tread depth with no apparent cracking, bulging, or other visible deterioration.

A tire technician who performed my state inspection indicated the tires appear serviceable from an external assessment standpoint. However, I understand there may be internal degradation factors not visible during standard inspection procedures.

What is the technical consensus on replacement timing for RV tires when age limits are reached but visible condition remains acceptable? Specifically looking for guidance on the 6-7 year replacement interval and whether internal rubber compound deterioration poses legitimate safety risks regardless of external appearance. …more

Called three different tire shops this month about my 2020 Newmar Ventana's Michelin 275/70R22.5 tires and all want them replaced just for being 6 years old despite perfect tread. I'm meticulous about tire maintenance - I check air pressure religiously before and after every trip, whether it's a short weekend getaway or an extended cross-country journey like the 5000-mile trip I just completed.

Despite my careful maintenance routine, I experienced a blowout on the right rear inside tire during the final leg of that recent long trip. When the roadside service technician came out to help, he recommended replacing all six tires specifically because of their age, even though the remaining tires still have plenty of tread depth and appear to be in excellent condition visually.

This has me confused because I've heard conflicting advice from other RV owners - some say well-maintained motorhome tires can safely last up to 10 years, while others insist on much shorter replacement intervals. I'm trying to understand what the actual safety guidelines are for RV tire replacement based on age versus tread wear. Should I really replace tires that still look good just because of when they were manufactured? What's the real story on how tire age affects safety, and how do I properly check the manufacturing date to make this decision? …more

After upgrading my 2015 Fleetwood Excursion M-35B from 255 to 275 width tires, it started getting sketchy handling on highway turns. The current 255/70R22.5 tires are wearing out and I'd love to go wider with 275/70R22.5 for better stability, but I keep getting conflicting advice from different tire shops.

Some say it's fine, others warn about clearance issues and potential problems. I really need to know what specific measurements I should check before making this change. What wheel width do I need? How do I verify there's enough steering clearance? I don't want to buy expensive tires only to find out they don't fit properly or aren't safe for my RV's load requirements. …more

Every time I look at those 2017 motorhome tires I replaced last week, I keep wondering if I jumped the gun when they still looked perfect. I recently purchased it and it came with the original Michelin tires, which puts them at about 7-8 years old now based on the DOT date codes. The previous owner was meticulous about storage - the RV was kept in a climate-controlled garage for most of its life and only has about 27,000 miles on it.

Here's what's puzzling me: these tires look absolutely pristine. I've inspected them thoroughly and can't find any visible signs of aging like sidewall cracking, dry rot, or unusual wear patterns. The tread depth is still excellent, and they hold air pressure perfectly. However, I keep reading conflicting information about tire age versus condition. Some sources say rubber degrades internally even when stored properly, while others suggest that well-maintained tires can safely exceed the typical replacement timeline.

I'm planning some extended travel in the coming months and want to make the safest decision. Should I replace these 7-8 year old Michelin tires even though they appear to be in excellent condition, or is it safe to continue using them based on their visual inspection and low mileage? What do RV tire experts generally recommend for the age-based replacement timeline? …more

Despite getting my tools ready and being determined to tackle this steering shimmy hitting my 1997 Class A motorhome at 55 mph — where should I start? Based on my troubleshooting, this appears to be a wheel balance issue, though I suspect there could also be tire wear patterns or front end component problems contributing to the vibration.

I need to locate commercial truck tire facilities in the Columbus, Ohio area that can properly handle motorhome wheel balancing services. Standard automotive shops don't have the equipment for larger RV wheels, so I'm specifically looking for commercial-grade tire service centers that can diagnose whether this is purely a balance issue or if there are additional front end problems requiring attention. …more

Around mile 50,000 my 2014 Tiffin Open Road 31 SA's dashboard warning lights started going haywire despite the manual saying each light indicates specific problems. I've got a lovely collection of warning lights glowing at me - specifically the yellow Hydromax, ABS, and red Brake warning lights. They all go off if I apply the brake first and then start the engine, but come back on when I release the brake.

I've already done some basic troubleshooting: checked all fluids (they're ok), e-brake is working, jacks recognize parking brake status, speed control works, and brake switch seems fine. I even tried unplugging the brake differential switch while the brake was depressed, which made the lights go off (except for the red brake warning).

So help a fellow road warrior out - how do I decode this dashboard light festival? What could be causing all three of these warning lights to come on simultaneously? …more

About every 6 months my 2016 Tiffin Allegro 36 UA is eating through brake rotors on this Ford F53 chassis with Dana 17060s rear axle. When I look up brake rotors using my VIN, everything shows 10-lug parts, but my RV actually has 8-lug rotors.

Why is the Ford VIN lookup giving me wrong brake rotor specs? Where should I be sourcing 8-lug brake parts for this Dana axle configuration instead? …more
