nail in tire

[zo6racerx]

When I got home today, I decided to come in through my garage. As I was walking into the house, I noticed my right rear tire was low. Sure enough, I must have picked up a nail. It is in the tread area. Would you repair it or just buy a new tire. I have 7K on the car, I guess I would have to buy two new rears?

There is a thread on this if you do a search, but you can have it repaired at a Goodyear dealer. He will put a plug on the inside of the tire and it will still be Z-rated if only repaired once. If you pick up another nail, you will have to replace the tire to be safe. Hope this helps.

Bob,
Thanks. I will stop by Goodyear tommorow

Have had several repaired where they use a patch that has a dart that comes through the tread. Never had a problem. I would name the store but it doesn't look like they are a supporting vendor anymore.

I had the same "nail in tire" issue last week. Went to a local Discount Tire. They pulled the nail, made a "lifetime guarantee" patch on inside of tire, remounted and balanced and charged me $0.00.

I was shocked...they said to come see them when I was ready for P2's or Nittos.

I did flip the service guy $10 (all I had in cash).

DISCOUNT TIRES KNOWS HOW TO TREAT THE Z OWNERS!!

two of my Kumho Ecsta MX's also picked up a nail(one each), two days apart!

I bought them at Discount Tire. They also used the inside patch with "dart" through the hole.

since I DE a lot, I was concerned with heat in tire, expansion, lot's of lateral movement of the tire, etc, possibly allowing a blowout during a hot session.

They took me back and showed me the entire process for repairing the tire and told me there is some tire standard(can't remember it), they are required to meet when doing tire repairs, and the repair will keep the Z rating completely in all respects, and not to worry.

love those guys.....

SUBJECT: Puncture Repairing and Retreading of Goodyear Speed-Rated Tires (Includes Extended Mobility Tires)
With the ever increasing popularity of Goodyear Speed-Rated tires, it is important for you and your customers to know how repairing and retreading will affect the speed rating.

Accordingly, the following information will enable you to discuss these important subjects with your customers.

I. SUMMARY STATEMENT


REPAIR
A Goodyear speed-rated tire may be repaired to correct a commonly repairable nail hole puncture in the tread area only, but proper materials and procedures must be applied. INCORRECT OR IMPROPER REPAIR WILL RESULT IN THE TIRE NO LONGER BEING SPEED-RATED BY GOODYEAR, and the Goodyear warranty may also be affected.


RETREADING
If a Goodyear speed-rated tire is retreaded, it no longer is speed rated by Goodyear.

II. DETAILED POLICY - Puncture Repair of Goodyear Speed-Rated Tires


The puncture must be confined to the tread area only.
(See "Repair Area", item III-B).

Restrictions on the number and size of repairs must be followed.
(See "Puncture Repair Limits" table, item III-C).

A detailed repair procedure must be followed.
(See "Repair Procedure", item III-E).

A Goodyear speed-rated new tire repaired in strict accordance with items II-A, B & C, will retain its speed rating.
III. REPAIR PROCEDURE FOR SPEED-RATED TIRES

GENERAL
The objective of the puncture repair is to seal the tire against loss of inflation pressure and to prevent damage to the carcass from moisture. In all puncture repairs approved by Goodyear, the hole must be filled with a plug, and a patch covering the hole must be applied according to repair material manufacturer instructions to the inside of the tire. Never repair tires which are worn below 2/32" tread depth.

NOTE: No tire is to be repaired without first being removed from the rim.


REPAIR AREA
Repairing is limited to the tread area only within the outside grooves. No repairs are allowed in the tread area beyond the outside grooves or sidewall.


PUNCTURE REPAIR LIMITS

TIRE SPEED
(SPEED SYMBOL) MAX. NUMBER
REPAIRS MAX. REPAIR
DIAMETER
130 mph and over
(H, V, Z) 1 1/4 in. (6mm)


Tires marked with an S, T, or U speed rating, and tires with no speed ratings may be repaired in accordance with the RMA "Puncture Repair Procedures for Automobile Tires" wall chart or Product Service Bulletin 98-12 dated August 28, 1998.


MATERIALS

Precured rubber plugs - 1/4" (6mm) diameter

Precured patches

Precured plug/patch combi-units

Chemical vulcanizing cement

Pre-buff cleaner

REPAIR PROCEDURE

CAREFULLY REMOVE THE TIRE COMPLETELY FROM THE RIM.

Locate the puncture on the inside of the tire and circle with crayon.

Remove puncturing object if it is still in the tire.

Carefully inspect tire on a good tire spreader, with ample light, which will show any cracks, breaks, punctures, damaged or broken beads.

Check liner for cuts, cracks, or holes which may cause the tubeless liner to lose air.

Check the injury with an inspection awl:

Determine size and angle of injury

Check for ply or belt separation

Reject any tire that has separation, loose cords, damaged bead(s), or any other non-repairable injury.

If the hole is simple and round, steps 9 through 17 of the puncture repair procedure will be successful.
NOTE: If the hole shows evidence of fabric splitting, such an injury cannot be properly repaired using this puncture repair procedure. Such an injury must be skived out and repaired as a section (reinforced) repair, which will maintain the serviceability of the tire, but will invalidate the tire's speed rating. If a section repair is necessary, the customer must be advised, before the repair is made, that the tire will lose its speed rating, and must not exceed operation at normal highway speeds.


Use a pre-buff cleaner and a scraper to remove contaminants from the liner in the area to be buffed around the injury.

Use a 7/32"carbide cutter for 1/4" repairs to clean out the puncture.

Make sure that the drill follows the direction of the puncturing object.

Always drill from inside to outside of tire.

Using chemical vulcanizing cement, lightly coat at least 1/2 of the tapered end of the repair plug. Install the plug in the prepared puncture according to the manufacturer's instructions. Trim the liner side of the plug slightly higher than the surface of the liner without stretching the plug.

Center the patch (or patch template) over the injury without removing the backing. Adhere to patch or template instructions, as to positioning as related to bead location. Mark around the outside edge of the patch, approximately 1/4" larger than the patch.

Buff the liner and plug at the puncture location. The buffed area should be slightly larger than the patch. The buffed surface should be finely grained (RMA 1 or 2 texture) and even for proper bonding. Use care to prevent burning the rubber with the buffing tool. Do not buff through the liner. Do not buff into the marking crayon.

Clean the buffing dust from the tire using only a vacuum or brush. Do not use gasoline or other petroleum solvents on the buffed area.

Coat the buffed liner surface and the patch with one evenly applied coat of chemical vulcanizing cement in accordance with the recommendations of the repair materials manufacturer. Allow the cement to dry thoroughly. Do not touch the cemented areas.

Install the patch with the beads of the tire in the relaxed position. Position the patch over the puncture according to the markings on the patch. Stitch the entire patch starting from the center, keeping the strokes close together to avoid trapping air under the patch.

Cut off the protruding end of the plug about 1/8" above the tread surface.

FINAL INSPECTION - The repair must seal the inner liner and fill the injury. After remounting and inflating check the repair, both beads and valve with a soap solution to assure a complete seal.

I had exactly the same experience. Of course their computer shows I've bought BFG All-Terrains for my Jeep and for my pickup in the last three years.

Even better, the balance job ended up with smaller weights than the factory balance -- they moved the tire on the rim. That is someone who cares.

that's great info and some good reading
