The Grand Prix 5000 tube-type tire in size 700x30 on a 19mm internal rim measure 30mm width and 27mm height, The 700x28 measures 27.7mm width and about 25mm high on similar rims, so the 30mm tire is true. The tires were within 10 to 15 grams of claimed weight. They mounted easily to tubeless ready rims with Pirelli Smart (thermoplasitc) tubes. Changed to these from Veloflex, which are equally nice hand-made tires because I wanted a larger tire without going up to 32mm, which just seem to be overkill for a pavement-only racing tire. 30mm is appreciated on the rougher sections but for most roads with alligator cracks or better pavement, 28mm still seems more appropriate for me (168 pounds). The 30mm provides a very plush ride at the expense of weight and aerodynamics (if you care).
For years I ran the Conti Gatorskin tires as I was convinced that I needed the extra puncture protection. After hearing so many good things about the Conti GP 5000s I decided to try them a few seasons ago. The GP 5000s are now my go to tire.
I run the GP 5000s with either latex or TPU tubes and I inflate according to the SILCA tire pressure calculator. The roads that I ride on are typically either smooth bike paths or pavement/asphault roads and highways that I would consider to be average to good condition (live in Nebraska, so we get our share of pavement break-up).
Over the 3-4 seasons that I have run the GP5000s I have not experienced any more punctures with these tires that I had with any other tire...they are extremely durable and reliable. With the miles that I ride, I will generally get 1 full season out of the tires, sometimes I can extend the front tire farther as it gets less wear. Besides the same durability as other tires, these tires are incredibly smooth and roll extremely well. I don't see any reason to consider changing to any other tires.
Continental has been my choice of tires for over 20 yrs. Started with the 4000 series 2003/2005 .They are still the best road tires for the type of long distance rides that i enjoy, 60+ mile days on paved roadways. I get between 5000/6000 miles on a set. I rotate them every 1500/2000 miles,depending on how well they are wearing which for me is about every 3 months. Not too much trouble as I have 2 sets of wheels mounted with these tires to swap out between. Running both sets tubeless.Wish the price were not so high,but I will still keep using them as I think they are the best tires for how I use them.
Placed these on a Giant Revolt Advanced 2 gravel bike to ride long distance on pavement on alloy factory wheels. Replacing tubeless 40mm gravel tires to a road tire 700c 32 black sidewalls. Got them for long charity ride Bike around the Bay 177 mi weekend ride, Florida rail trail vacations. Daily training rides consist of 20-30 mi rides. Wide enough to soak up sidewalk cracks, and anything else flat I want to ride across in comfort. Paired with Conti race tubes. Total system weight rider and bike 250 lbs, pressures front 65 psi rear 68 psi. No flats during the training and charity ride avoiding broken glass on my rides as I see it in the path as well as I can. I ride mostly concrete bike paths, and asphalt. Do not take these on a small gravel walking paths or off the road they will tear up the side walls. Rubber is slightly tacky I only use in dry conditions good traction. There are two tread wear dimples near the logo find their location so you know where to look for them when your tire wears out for replacement, if similar wear to tubeless S TR I'd expect about 3400 mi. before replacement in my environment hot n humid. Been using Conti products for 25 years haven't diverted to other tire makers because they have not given me a reason to. Pricey, catch them on sale, use your points.
