Optimum Tire Protection & Coating Review

Recommended Posts

Dr G suggested that some tire compounds don't work well with TPC, whether it's release agents or chemicals added to the rubber for elasticity, the applications are problematic.  Next time I will really concentrate on cleaning and use maximum amount of TPC to flood the ribs.  I may try a different brush, the one I use is designed for tires but the bristles are medium soft - may try a wire style.

I have noticed the same issue of blotchy application depending on tire manufacturer and how new the tires are.  Worst application was on new Nokian Entyre 2.0 on my wifes mini-van.  Ended up applying 2.5 coats to try and get even coverage (third application only touch up).  The ribbed sidewall also made it difficult.  On Bridgestone Blizzaks (two years old)  I had reasonably good application at 1.5 coats (second minor touch up).  I generally have the best success of even coverage on Michelin tires ( 1 coat on 3 year old Pilot SuperSport and 1.5 coats on new X-Ice Snow).

Based upon my experience, I will probably avoid applying to tires with ribbed sidewalls as it does not improve the look or improve the maintenance significantly over Optimum Tire Bond.  The main advantage of TPC is when applied correctly it virtually eliminates any tire browning for six months so that you basically can clean with ONR.  When you have ribbed sidewalls, dirt gets trapped that you still should be using APC to clean tires.

For application of TPC, I use some of the cheapest microfiber towels you can find at Walmart (11% Polyamide and 89% polyesters).  You generally want low polyamide content to avoid TPC being absorbed in the microfiber towel.  I also cut the the towels into quarters (roughly 6 inch by 6 inch) then fold over once on one side and twice on other side making a 3 inch wide by 1.5 inch applicator.  I find this makes a nice edge for TPC to most tires.  I will typically use a clip to hold the applicator so I can more easily control and prevent the applicator from unfolding.

Second attempt with TPC and ribbed tires - I attacked my last car with some different methodology using suggestions from Dr G and Detail Mutant.  These tires are also ribbed Continentals but are 4 years old.  I started by:

cleaning with instant detailer ratio ONR

Applied TAR, rinsed with ONR (this was a new step - the TAR really helped clean the rubber)

100% Power Clean, rinsed with ONR

2nd application of 100% Power Clean, rinsed with ONR.  Tires looking good after the cleaning.

allow to dry overnight, do another ONR wipe down and allow to dry

Apply generous amounts of TPC using the Dual Foam Applicator (Dr Gs recommendation).  Was hard on the foam applicator but allowed better coverage than microfiber.

Results - much better, good coverage and no blotchy areas, will now monitor durability.

Follow up on past applications (even the blotchy one) - tires look better than untreated but after several weeks, including several rainstorms and pollen season, they lost some shine.  The good news, a wipe down with ONR returned them to 70% of the fresh treated look, probably equal to Opti-Bond.  So far so good

Glad you got better results this time, Ron.  As I noted previously, I use a cheap (foam) tire swipe, so it doesn't bother me if it gets torn up, it was 50 cents, works well.
