The difference between radial- and bias-ply tires lays in the way the belt layers are set within the molds when the tires are cast. Radial tires have the primary belts set at approx. 90 degrees to the direction of rotation. When a load is put on the tire, the belts channel the deflection forces more or less directly from the contact point, through the sidewall, to the rim. This results in a contact patch which is relatively supple and can change shape readily to maintain optimum traction.
Bias-ply tires, on the other hand, have the primary belts layered at an angle to the direction of rotation. This results in a stiffer carcass form which retains it's shape better, but any deflection forces are channeled through the belting in such a way that it results in minor deflection of the carcass at points away from the contact patch.
Radial tires provide greatly improved traction and ride when compared to Bias-ply. I would expec if they were mixed, the difference would become apparent as speeds increased. As loads increase on the tires, the radial tire would maintain fairly consistent grip, while the bias-ply would start to feel increasingly "greasy", losing traction in a gradual manner which would make handling unpredictable as speeds varied.
Short answer: bad idea.
As far as hydroplaning and wet traction, that is more dependent on tread design and specific rubber compounds used than carcass construction.
If you want to see the difference in how tires react at the limit, find videos of some roadracing in the '60s and '70s, when tires were predominantly bias-ply construction, and take note of the way the cars corner: sideways. Then find a video of a modern-day vintage race event for muscle cars or such. Same types of vehicles, the difference is that they are typically fitted with radial tires now (albeit with better tread compounding as well). I think you'll find speeds higher and handling much more composed on the same cars running modern radials.

Is it safe to use radial tube with non-radial tire?
You can use a radial tube in a bias ply tire BUT you can not use a bias tube in a radial tire. The sidewall flex of a radial tire is greater than that of a bias ply. A bias tube cannot flex as rapidly as a radial tube and so the resulting friction or rubbing create too much heat and the tire/tube combination will blow.
Which type tire is better for an explorer bias or radial?
Radial is better.
What are the differences between radial and bias ply tubes?
Bias tires were the standard until the radial tire became the norm. The difference is in how they are constructed. Bias tires were typically constructed of 4 plys that run at angles to each other and the body of the tire and cross each other. Radial tires have the belts at a 90-degree angle to the tire, and the belts overlap rather than cross each other. Radial tires have another belt, usually of steel cord, running around the tire under the tread. Radial construction allows the sidewall of the tire to flex under loads without affecting the contact of the tread with the road unlike a bias tire that flexes very little. It is this flexing that requires you to use a radial tube in a radial tire. The tube is designed to handle the flexing without overheating as a bias tibe would.
What is bias ply?
Instead of using steel belts (the way a radial tire does), the tire is entirely rubber.
What is a Difference between a bias - ply tire and a radial tire?
Radial tires are worlds beyond bias ply tires. In radial tires, the steel chords are placed in a criss-cross pattern. Whereas bias ply tires are placed flat across the face of the tire. Bias ply tires are much, much harder for the engine to turn and are much harder for the suspension to compensate for. Bias ply tires are almost no longer used. That goes for America at least.
What is the difference between 23.5-25 and 23.5R25 tires?
23.5-25 is bias ply tire 23.5r25 is radial tire
Can radial tires get flat spots from sitting to long?
Bias ply tires get a flat spot from sitting but I have yet to see a radial tire do that.
Can you put a radial tire on a bias rim?
There is no such thing as a bias rim. There are bias ply/belted tires and radial belted tires. Tires have a rim size as part of the tire size molded into the sidewall. metric radial size would be something like 195/60R15. The R designates radial and the 15 isa the rim size in inches. A bias tire would have size listed as something like an FR78-15. The 15 again is the rim size in inches. Any tire designed for a 15 inch rim will fit as long as it's not too wide or narrow. They may still fit but not quite properly.
What is the difference between bias and radial tires?
The difference is in the way the body cords are put in the tire . A bias tire has the body cords (plies) on an an angle (bias) to each other. A radial tire has the body plies running parallel. The advantage of a radial tire is that it runs cooler, making it last longer. A bias tire does not "bulge" at the bottom so it is not as prone to be damaged as easly to curb scuffing.There are two types of tires mostly used in cars and commercial vehicles: Radial and Bias.Bias Ply tire: This type of tire has diagonal or bias plies. These plies crisscross. This makes tire strong in all directions because of the plies overlap.Radial ply tire: In a radial tire, the ply cords run in the radial direction. The plies run parallel to each other and vertical to the tire bead. Stabilizer belts are applied over the plies to give extra strength parallel to beads.Now we look at advantages of radial tire over a bias tire:Good high speed capacityLonger lasting and Longer tread life (Up to30%- 50% longer)Steel Belted - Results in tougher overall constructionBetter floatation ,larger contact area wider footprintLow heat build-up or run coolerLower rolling resistanceBetter Fuel EconomyBetter stabilityWear resistantSmoother, more quiet rideDisadvantage of radial tire over a bias tire:More prone to puncturing at side wallsSide wall bulgingMore difficult to repairHigher purchase priceHeavier steering at low speeds but power steering facility is there so it is acceptable.So mostly in all modern cars radial tires are used.
Are Goodyear F78-15 tires bias or radial?
They are most likely bias ply, from the info you have given. There are typically 3 numbers on a tire & radial tires will have an "R" designation prior to the 3rd number such as: P245-60-R14.
What is meant by star rating for ply in Off the Road tires?
The load capacity of a tire is indicate by the star rating (in case of radial tire) and the ply rating (in cse of bias tire).
