Purpose of Study

The purpose of the rear agriculture tire research was to determine the average life span of a farm tire so Tire Stewardship Manitoba (TSM) can use this information in consideration for setting appropriate eco-fees on these OTR (Off The Road) tires.

Method of Study

The research was done through OTR Recycling and Reliable Tire Recycling, by taking digital photos of a tire’s sidewall. The tire’s sidewall, will list information including the date and manufacturing plant code, implementation rating, ply rating, and a tire mould code. Each code was then entered into a Microsoft Excel spreadsheet to be reviewed and analyzed.

The Agricultural Tire

There are a few ways to separate an agricultural tire from other OTR tires. The ply rating that is listed on the tire should be a relatively lower number and should not exceed 12 ply, to stand as an agricultural tire. These tires have a smaller ply rating because they need to be significantly lighter, so no extra weight is applied to the farmer’s field and helps to prevent damage to the crop.

Another way of identifying an agricultural tire is by examining the tread markings. The

Agricultural tire will have more spaces between treads; this is so there will be less contact to the farmer’s field which prevents the soil from becoming compressed. Although this is a way of recognizing an Agricultural tire from other OTRs it is not the most accurate way to identify between tires.

The most accurate way to determine which category a tire will fit in is through the implementation rating. There are roughly twenty-three different implantation ratings for

Agricultural tires, with R-1 appearing to be the most used.

Manufacturers’ Date Codes

Date codes on tires can be an important indicator, as manufacturer’s base a tire’s warranty on the date of purchase opposed to tread wear. When dealing with a Goodyear tire

(the agricultural sector was sold to Titan) the date code is standardized by a stamp in the tire that should begin with a collection of letters starting with PK, and finishing with a separate stamp that consists of either three or four numbers, which indicate the week and year of manufacture. This format of coding has not changed through the transfer of agriculture ownership, except for the two beginning letters, which can vary due to different plant manufacturing locations.

Titan indicates their manufacturing date by CF then a stamp embedded into the tire which will consist of four digits the first one stands for the decade year the second and third digits stand for the week and lastly the final number is needed to complete the year. Although

I was not able to speak to someone from Armstrong because they no longer exist it appeared that they used the same type of coding as Titan.

B.F. Goodrich based its coding on an Alphabetized table; the first three letters indicated the plant, week, and year. Although I was provided information for B.F. Goodrich coding, when decoding this brand of tires I was not able to identify a date code because no coding met this coding pattern. Firestone displays their date coding visibly by VE00000 then a collection of either three or four digits that again indicate the week and year of the manufacturing date.

While researching the date codes, I ran into a few difficulties decoding the data, such as; agricultural tires are not certified to travel on roads therefore are not required to be equipped with a DOT (Department of Transportation) code, which poses the issue of the manufactures not being required to visibly declare the tires date and allows for alphabetized year charts, that will not be sent out for review. Another issue that was faced was over the years some companies had sold their agriculture tire sector to other companies, which caused some problems when speaking to people who did not work with the previous company. I also spoke to some OTR dealers within the surrounding areas of Winnipeg, but the dealers also had no

6 Rear Ag Tire Research Report knowledge about reading the date codes, aside from the codes consisting of three or four digits. When speaking to different warranty people within agriculture manufacturers as well as the OTR warranty sector little answers were given, so it was needed to repeat calls and speak to someone new.

Due to some of the difficulties that were encountered while researching the correct formats for dates some companies formats had to be assumed including; Alliance, Armstrong,

Concept, Co-op, Denman, Galaxy, General, Industrial Lug, Kelly-Springfield, Maxi-Trac, MDG,

Michelin, Pirelli, Power Glide Rib, Power Mark, Ranger, Summit, Versatorque, Wide Wall, and

Yokohama. Although these companies date codes were assumed, the formats appeared similar between companies. The Excel spreadsheet was also e-mailed to others such as; David

Lamb, Abe Penner, Vic Heibert, Moe Tressor, and Ashley Leibl to help assess the unknown date codes.

After exhausting many possible research avenues, there were 150 sidewalls marked with codes that could not be distinguished, and are defined by this study as “un-decoded”. It has been suggested that these tire code samples could not be decoded because they are possibly too old for anyone to know the coding method that was used. This is possible, but a more likely explanation is that these tire codes’ significance, either as the date of manufacture or as some other indicator related to the tire, was not reported by the manufacturer for this study as date codes on agricultural tires are not mandated.

7 Rear Ag Tire Research Report Sample Size

A total of 949 tire sidewalls were documented by this study. The original sample size dropped significantly when 148 sidewalls were categorised as industrial; 150 sidewalls were listed as “un-decoded”; and 88 sidewalls documented were determined to be the wrong side of the tire which lists no possible date codes. As such, the original sample size of 949 tire sidewalls was reduced to 559 date codes that could be appropriately measured for this study.

Conclusion: Agricultural Tire Life in Manitoba

The end of a tire’s life is due to weathering and not decreased tread wear. Based on the information obtained by this study of scrap agricultural tires, the mean service life of an agricultural tire in Manitoba is 17.44 years.
