Can you substitute 195-55-15 tires for 185-55-15 tires if so which tire rides better'?

Yes, you can substitute 195/55-15 tires for 185/55-15 tires, but it may affect handling and comfort. The 195 tires are wider, which can provide better grip and stability, but may also result in a firmer ride due to a larger contact patch with the road. In general, the 185 tires might offer a softer ride, as they have a slightly smaller contact area. Ultimately, the choice depends on your driving preferences and vehicle specifications.
